ITEM 9A. CONTROLS AND PROCEDURES Evaluation of Disclosure Controls and Procedures Our management, with the participation of our Chief Executive Officer (principal executive officer) and our Chief Financial Officer (principal financial officer), has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Annual Report to ensure that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that information required to be disclosed in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures. Based on this evaluation, our management concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of December 31, 2021 due to the material weaknesses described below. As further discussed below under “Management’s Report on Internal Control Over Financial Reporting,” management has identified material weaknesses in our information technology (IT) general controls (collectively, “ITGCs”) and related IT-dependent process level controls and business combination accounting controls, which are part of our internal control over financial reporting. We have developed a remediation plan for each weakness, which is described below under “Remediation.” Further, the report of our independent registered public accounting firm for the fiscal year ended December 31, 2021, Marcum LLP, regarding its audit of our internal control over financial reporting as of December 31, 2021, which is included below under the heading “Report of Independent Registered Public Accounting Firm on Internal Control over Financial Reporting”, expresses an adverse opinion on our internal control over financial reporting as of December 31, 2021. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost benefit relationship of possible controls and procedures. Changes in Internal Control We periodically review our internal control over financial reporting as part of our efforts to ensure compliance with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002. In addition, we routinely review our system of internal control over financial reporting to identify potential changes to our processes and systems that may improve controls and increase efficiency, with the goal of establishing and maintaining an effective internal control environment. Changes may include such activities as implementing new, more efficient systems, consolidating the activities of business units, migrating certain processes to our shared services organizations, formalizing policies and procedures, improving segregation of duties and increasing monitoring controls. In addition, when we acquire new businesses, we incorporate our controls and procedures into the acquired business as part of our integration activities. During the fiscal year ended December 31, 2021, we completed acquisitions of two significant subsidiaries, Whinstone and ESS Metron, and began the process of integrating these acquired businesses into our own, including incorporating our system of internal controls and procedures with those of our acquired businesses. As part of our integration of these acquired businesses, we are in the process of incorporating our controls and procedures with respect to Whinstone’s and ESS Metron’s operations, which we expect to complete as of December 31, 2022. Other than the system and related process changes associated with these two acquisitions, there have been no changes in our internal control over financial reporting that occurred during the fiscal year ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 54 Management’s Report on Internal Control over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of annual or interim consolidated financial statements will not be prevented or detected on a timely basis. Our management excluded from its assessment of effectiveness of our internal control over financial reporting the internal controls of our two recently acquired significant subsidiaries, Whinstone, which we acquired as of May 26, 2021, and ESS Metron, which we acquired as of December 1, 2021. We have included the financial results of these subsidiaries in the consolidated financial statements from the date of acquisition. Total assets (excluding goodwill and intangible assets, net) and total revenues related to Whinstone and ESS Metron that were excluded from our assessment of internal control over financial reporting collectively represented approximately 20.4% and 13.5% of our consolidated total assets and total revenue as of and for the year ended December 31, 2021, respectively. Our management will include the internal controls of Whinstone and ESS Metron in its assessment of the effectiveness of our internal control over financial reporting as of December 31, 2022. Management utilized the criteria established in the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) to assess the effectiveness of our internal control over financial reporting as of December 31, 2021. Based on this evaluation, management identified the following weaknesses in internal control over financial reporting as described below: 1) The Company did not design and/or implement user access controls to ensure appropriate segregation of duties that would adequately restrict user and privileged access to the financially relevant systems and data to the appropriate Company personnel. 2) The Company did not design and implement program change management controls for certain financially relevant systems to ensure that IT program and data changes affecting the Company’s (i) financial IT applications, (ii) digital currency cold storage wallets and mining equipment, and (iii) underlying accounting records, are identified, tested, authorized and implemented appropriately to validate that data produced by its relevant IT system(s) were complete and accurate. Automated process-level controls and manual controls that are dependent upon the information derived from such financially relevant systems were also determined to be ineffective as a result of such deficiency. 3) The Company did not properly design or implement controls to ensure that data received from third parties is complete and accurate. Such data is relied on by the Company in determining amounts pertaining to revenue – mining and cryptocurrency assets held is complete and accurate. Automated process-level controls and manual controls that are dependent upon the information derived from such financially relevant systems were also determined to be ineffective as a result of such deficiency. 4) The Company did not properly design and implement controls to ensure that certain inputs and assumptions utilized in the valuation of intangible assets identified in its accounting for business combinations were reasonable in the circumstances. Such deficiency also resulted in material adjustments required to the Company’s provision for income taxes. These material weaknesses create a reasonable possibility that a material misstatement to our consolidated financial statements or disclosures would not be prevented or detected on a timely basis. Our independent registered public accounting firm, Marcum LLP, has issued an audit report on management’s assessment of internal control over financial reporting as of December 31, 2021. The report of Marcum LLP, which expresses an adverse opinion on the Company’s internal control over financial reporting as of December 31, 2021, is included below under the heading “Report of Independent Registered Public Accounting Firm on Internal Control over Financial Reporting”. Remediation Our Board of Directors and management take internal control over financial reporting and the integrity of our financial statements seriously. Management continues to work to improve its controls related to our material weaknesses, specifically relating to user access and change management surrounding the Company’s IT systems and applications. Management will continue to implement measures to remediate material weaknesses, such that these controls are designed, implemented, and operating effectively. The remediation actions include: (i) enhancing design and documentation related to both user access and change management processes and control activities (ii) developing and communicating additional policies and procedures to govern the area of IT change management (iii) develop robust processes to validate all data that is received from third-parties and relied upon to generate financial statements. In order to achieve the timely implementation of the above, Management has commenced the following actions and will continue to assess additional opportunities for remediation on an ongoing basis. ● Engaging a third-party specialist to assist Management with improving the Company’s overall control environment, focusing on change management, access, and financial reporting controls ● Implementing new applications and systems that are aligned with Management’s focus on creating strong internal controls, as well as complete and accurate financial statements ● Implementing more robust policies and procedures, relating to third-party data as well as the inputs and assumptions utilized in estimates, including in business combination valuations and assessments, to ensure the reliability of controls and financial reporting ● Continuing to increase headcount across the Company, with a particular focus on hiring individuals with strong SOX and internal control backgrounds. However, the material weaknesses in our internal control over financial reporting will not be considered remediated until other ITGCs and process-level controls operate for a sufficient period of time and can be tested and concluded by management to be designed and operating effectively. We cannot provide any assurance that these remediation efforts will be successful or that our internal control over financial reporting will be effective as a result of these efforts. In addition, we continue to evaluate and work to improve our internal control over financial reporting related to the identified material weaknesses, management may determine to take additional measures to address control deficiencies or determine to modify the remediation plan described above. 55 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON INTERNAL CONTROL OVER FINANCIAL REPORTING To the Stockholders and Board of Directors of Riot Blockchain, Inc. Adverse Opinion on Internal Control over Financial Reporting We have audited Riot Blockchain Inc. and Subsidiaries’ (the "Company") internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, because of the effect of the material weaknesses described in the following paragraph on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. A material weakness is a control deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in “Management’s Annual Report on Internal Control Over Financial Reporting”: 1) The Company did not design and/or implement user access controls to ensure appropriate segregation of duties that would adequately restrict user and privileged access to the financially relevant systems and data to the appropriate Company personnel. 2) The Company did not design and implement program change management controls for certain financially relevant systems to ensure that IT program and data changes affecting the Company’s (i) financial IT applications, (ii) digital currency cold storage wallets and mining equipment, and (iii) underlying accounting records, are identified, tested, authorized and implemented appropriately to validate that data produced by its relevant IT system(s) were complete and accurate. Automated process-level controls and manual controls that are dependent upon the information derived from such financially relevant systems were also determined to be ineffective as a result of such deficiency. 3) The Company did not properly design or implement controls to ensure that data received from third parties is complete and accurate. Such data is relied on by the Company in determining amounts pertaining to revenue-cryptocurrency mining and cryptocurrency assets held is complete and accurate. Automated process-level controls and manual controls that are dependent upon the information derived from such financially relevant systems were also determined to be ineffective as a result of such deficiency. 4) The Company did not properly design and implement controls to ensure that certain inputs and assumptions utilized in the valuation of intangible assets identified in its accounting for business combinations were reasonable in the circumstances. Such deficiency also resulted in material adjustments required to the Company's provision for income taxes. These material weaknesses were considered in determining the nature, timing and extent of audit tests applied in our audit of the fiscal 2021 consolidated financial statements, and this report does not affect our report dated March 16, 2022 on those financial statements. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets as of December 31, 2021 and 2020, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2021, and the related notes, of the Company and our report dated March 16, 2022 expressed an unqualified opinion on those financial statements. 56 Explanatory Paragraph – Excluded Subsidiaries As described in “Management’s Annual Report on Internal Control Over Financial Reporting”, management has excluded its wholly-owned subsidiaries, Whinstone US, Inc. and Ferrie Franzmann Industries, LLC (d/b/a ESS Metron), from its assessment of internal control over financial reporting as of December 31, 2021 because these entities were acquired by the Company in business combinations during 2021. We have also excluded Whinstone US, Inc. and ESS Metron from our audit of internal control over financial reporting. These subsidiaries’ combined total assets and total revenues represent approximately 20.4% and 13.5%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2021. Basis for Opinion The Company's management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements. Because of the inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that degree of compliance with the policies or procedures may deteriorate. /s/ Marcum llp Marcum LLP Los Angeles, CA March 16, 2022 57 ITEM 9B.

Effective May 24, 2021, Mr. Yi was appointed Executive Chairman of the Board, a role in which he serves as both Board chair and as an executive officer of the Company. The Board determined to appoint Mr. Yi as Executive Chairman to better allow the Company to leverage his considerable knowledge of the Company, leadership abilities, and corporate governance, executive and capital markets experience to help it carry out the strategic initiatives set by the Board.

Mr. Les holds a Bachelor of Science in Information & Computer Science from U.C. Irvine. We believe Mr. Les is qualified to serve as a director on Riot’s Board based on his knowledge of the Company, his service as its Chief Executive Officer and, before that, as a director on the Board, and because he has been an active participant in the cryptocurrency industry since 2013. Mr. Les brings technical expertise regarding Bitcoin mining and protocol development, as well as his astute understanding of the overall Bitcoin industry and his commitment to educating the public about Bitcoin and Bitcoin mining, to Board discussions and strategic policymaking decisions that help the Board establish, oversee and improve Company policies designed to drive growth of the Company and protect stockholder interests. Board Composition The Company’s business affairs are managed under the direction of our Board. The Board consists of five members, including three independent directors, Hannah Cho, Hubert Marleau, and Lance D’Ambrosio, whom the Audit Committee has determined are “independent directors” within the meaning of the Nasdaq Rules and applicable SEC rules and regulations, and two non-independent, executive directors, Benjamin Yi and Jason Les. Under our Bylaws, the Board is divided into three classes (Class I, Class II and Class III) serving successive three-year terms, with only one class of directors being elected in each year However, because the classified board structure provided under our Bylaws was not previously in effect when it was enacted at the annual meeting of stockholders held in fiscal year 2021, these successive three-year director terms will be enacted on a rolling basis at the annual meeting of stockholders to be held in fiscal year 2022 and the annual meeting of stockholders to be held in fiscal year 2023. Accordingly, the Board is divided into the following three classes: ● Class I Directors , which presently consists solely of Mr. Hubert Marleau, whose current term as a director is set to expire at the Company’s annual meeting of stockholders to be held in fiscal year 2022. At the 2022 annual meeting of stockholders, stockholders will be asked to elect each individual nominated to stand for election as a Class I director for a term that would be set to expire at the Company’s annual meeting of stockholders to be held in fiscal year 2025; ● Class II Directors , which presently consists of Ms. Hannah Cho and Mr. Lance D’Ambrosio, whose current terms as directors are set to expire at the Company’s annual meeting of stockholders to be held in fiscal year 2023, when stockholders will be asked to elect each individual nominated to stand for election as a Class II director for a term that would be set to expire at the Company’s annual meeting of stockholders to be held in fiscal year 2026; and ● Class III Directors , which consists of Messrs. Benjamin Yi and Jason Les, whose current terms as directors are set to expire at the Company’s annual meeting of stockholders to be held in fiscal year 2024, when stockholders will be asked to elect each individual nominated to stand for election as a Class III director for a term that would be set to expire at the Company’s annual meeting of stockholders to be held in fiscal year 2027; At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of their election and qualification until the third annual meeting of the Company’s stockholders following their election and until their successors are duly elected and qualified.

EXECUTIVE COMPENSATION Compensation Discussion & Analysis The following discussion and analysis of compensation arrangements of our named executive officers for the year ended December 31, 2021 should be read together with the compensation tables and related disclosures set forth below. This discussion contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act that are based on our current assumptions, expectations and beliefs regarding future events affecting our compensation programs. Actual events may differ materially from our current assumptions, expectations and beliefs, and thus, the forward-looking statements contained in the following discussion may prove inaccurate. For more information regarding the forward-looking statements used in this section and elsewhere in this Amendment No. 1, see the Cautionary Note Regarding Forward-Looking Statements at the forepart of the Original Form 10-K. The following discussion and analysis relates to the compensation of our named executive officers (within the meaning of Item 402(a)(3) of Regulation S-K) for the year ended December 31, 2021. The 2021 compensation provided to our named executive officers is detailed in the Summary Compensation Table and the subsequent tables, as well as the accompanying footnotes and the narrative disclosures following the tables. While the following discussion and analysis is focused on our named executive officers for 2021, much of the discussion and analysis applies broadly across our executive ranks. Our named executive officers for 2021 were: Name Position Jason Les Chief Executive Officer (principal executive officer) Jeffrey G. McGonegal Chief Financial Officer (principal financial officer) Benjamin Yi Executive Chairman Megan M. Brooks Chief Operating Officer (former) (1) William R. Jackman General Counsel and Corporate Secretary (1) Effective April 7, 2022, Ms. Brooks resigned from her position as Riot’s Chief Operating Officer and from all other positions she held with the Company. 65 Compensation Philosophy and Objectives Compensation Philosophy We believe our people are the core driving force behind our long-term success. Our compensation philosophy is designed to align compensation with the Company’s business objectives and the creation of stockholder value.. Accordingly, we compensate our executive officers with a mix of cash salaries, annual performance-based cash bonuses based on the executive officer’s individual performance, and time-based equity and performance-based equity awards granted under the Company’s 2019 Equity Plan. These equity awards are generally awarded as grants of restricted stock units (“RSUs”) that vest, in the case of RSUs subject to a service requirement, in connection with the recipient’s continuing service with the Company though the designated vesting date for the applicable award or portion of the award, and in the case of performance-based awards, upon the Company’s achievement of certain performance metrics, as determined by the Compensation and Human Resources Committee as the administrator of the Company’s 2019 Equity Plan. We believe granting our executives (and our employees more generally) equity compensation encourages them to operate like owners, linking their financial interests with the interests of our stockholders. As the Company grows, we will continue to evaluate our compensation philosophy and programs to ensure they continue to meet our objectives. Compensation Objectives We designed our compensation program for all employees, including our named executive officers, to support our four main compensation objectives: ● Market Competitiveness : Ensure our ability to recruit and retain the most talented people in a competitive market; ● Performance Focused : Motivate our employees to deliver the highest level of performance over the short-, medium-, and long-term by making a substantial percentage of total executive compensation variable, or “at risk”, based on individual or Company performance; ● Balanced : Pay for performance metrics designed to ensure our mix of fixed and variable, “at risk” compensation fairly balances with our goals of attracting and retaining top talent, while motivating employees to be high-performing through an appropriate balance of short-, medium-, and long-term incentive awards ; and ● Alignment with Stockholders : Align employee and stockholder interests by collectively sharing in long-term success by granting employees time-based and performance-based equity awards to motivate them to continually deliver the highest level of performance to drive the Company’s strategic objectives forward. Compensation-Setting Process Compensation and Human Resources Committee’s Oversight of Executive Compensation The Board has delegated to its Compensation and Human Resources Committee the authority and responsibility for evaluating, overseeing, and approving the Company’s executive compensation, and for overseeing and administering the Company’s compensation policies and programs, including administering the Company’s 2019 Equity Plan and its other employee benefit plans and programs. When evaluating the compensation of our executive officers, the Compensation and Human Resources Committee evaluates factors including the executive’s responsibilities, experience and the competitive marketplace. The Compensation and Human Resources Committee may also invite the Company’s senior executives and other members of management to participate in its deliberations, or to provide information to the Compensation and Human Resources Committee for its consideration with respect to such deliberations, except that no named executive officer may not be present for the Compensation and Human Resources Committee’s deliberations of, or voting to approve, his or her compensation. Named executive officers may, however, be present for the deliberation of, or the voting to approve, the compensation for any other officer. The Compensation and Human Resources Committee has authority to retain such compensation consultants, outside counsel and other advisors as the Compensation and Human Resources Committee in its sole discretion deems appropriate. 66 Use of Compensation Consultants On an annual basis, the Compensation and Human Resources Committee directs its compensation consultant, Meridian Compensation Partners (“Meridian”), to review the Company’s compensation practices. Based on Meridian’s assessment, the Compensation and Human Resources Committee determines whether the overall executive compensation program is consistent with our business strategy and objectives and promotes our compensation philosophy. The Compensation and Human Resources Committee also takes into account the performance, experience, skills, level of responsibility and future potential of each named executive officer rather than adhering to a specific benchmarked percentage for any of our named executive officers. Role of Stockholder “Say-on-Pay” Advisory Votes We hold a stockholder advisory “say-on-pay” vote regarding the compensation of our named executive officers for the immediately preceding fiscal year, giving our stockholders the opportunity to weigh in on our named executive officers’ compensation as a whole. While these “say-on-pay” votes are advisory in nature, the Compensation and Human Resources Committee values the input of our stockholders and takes the results of these annual votes under strong consideration when evaluating the effectiveness of the Company’s executive compensation practices. Key Elements of Executive Compensation The Company operates in a highly competitive and rapidly evolving industry. Our goal is to align our executive compensation program with creating long-term value for our stockholders. The key elements of our executive compensation include: ● Base Salary : We pay a base salary that retains our executive management team in this competitive landscape. Each of Benjamin Yi and Jason Les also receive a fixed number of Bitcoin as part of their base salary, which we believe further aligns the interests of our leadership with the long-term objectives of the Company and those of our stockholders. ● Annual Cash Bonus Incentive Plan. The Compensation and Human Resources Committee and the Board has adopted an annual cash bonus incentive plan (the “AIP”), pursuant to which eligible employees are awarded annual cash bonuses generally tied to their annual base salary for the year. W e use annual cash incentive bonuses for our named executive officers and other applicable employees to tie a portion of their compensation to financial and operational objectives achievable within the applicable fiscal year. Additional details regarding the AIP are provided under the heading “ Annual Incentive Plan (AIP) ” in this Item 11 below. ● Equity Compensation: We use awards of equity compensation to reward long-term performance and incentivize future performance of our executive officers and other employees and service providers. We believe that providing a meaningful portion of the total compensation package in the form of equity awards aligns the incentives of our executive officers, employees and other service providers with the interests of our stockholders and motivates and helps retain our executive officers and other personnel. Equity awards are granted under the 2019 Equity Plan. We typically grant awards of equity compensation under the 2019 Equity Plan in two forms: 67 o Time-Based Restricted Stock Units . Under the 2019 Equity Plan, the Compensation and Human Resources Committee authorizes and administers grants of time-based restricted stock units (“RSUs”). RSUs represent the right to receive one share of Riot’s Common St ock for each vested RSU, subject to a continued service requirement. RSUs typically vest in equal quarterly tranches following the grant date, subject to continued service through each vesting date. Because RSUs vest depending on the award recipient’s continuous service with the Company through the vesting date, we believe RSUs provide a strong incentive to award recipients to remain with the Company for the long term, helping the Company retain the top talent needed to continue advancing on the Company’s strategic objectives. Further, because the value of RSUs depends on the market price of the Company’s Common Stock at the time vested RSUs are settled in shares of Common Stock, we believe RSUs help to better align the interests of our employees, named executive officers, directors, and service providers with those of our stockholders. and o Performance-Based Restricted Stock Units . In August 2021, the Compensation and Human Resources Committee and the Board adopted a performance-based restricted stock unit plan (the “Performance Plan”) under the 2019 Equity Plan, pursuant to which performance-based restricted stock units (“PSUs”) are granted to eligible employees. PSUs represent the right to receive one share of the Company’s Common Stock for each vested PSU. Each eligible employee is granted a “Target Award” of unvested PSUs when she or he is added to the Performance Plan, which are eligible to vest upon the Company’s achievement of Performance Objectives throughout the Performance Period, subject to the recipient’s continued service with the Company through each vesting date. In 2021, all of our named executive officers received a grant of PSUs under the Performance Plan. Annual Incentive Plan (AIP) Each year, the Compensation and Human Resources Committee establishes performance targets, target bonus amounts (generally as a percentage of the applicable employee’s base salary for the year), target award opportunities and other terms and conditions of annual cash bonuses for each of our named executive officers and employees eligible to participate in the AIP. Generally, employees become eligible to participate in the AIP after completing 90 days of continuous employment with the Company, and eligible employees must remain employed through the date the AIP bonus is paid to receive the cash incentive bonus for that year, subject to the terms of individual employment agreements and the Company’s Change In Control Policy. See “Change In Control Policy” under this Item 11 below. The target amounts set by the Compensation and Human Resources Committee relate to quantitative performance measures, such as the number of Bitcoin the Company mines during the applicable year, and qualitative performance measures, such as the achievements of a manager’s team during the applicable year. The Compensation and Human Resources Committee has substantial flexibility in establishing performance objectives, thresholds, targets, and maximums each year. Following the end of each year, the Compensation and Human Resources Committee will determine the extent to which the performance targets were achieved and the amount of the award that is payable to the executive officers. For fiscal year 2021, the Compensation and Human Resources Committee set the target amount at 100% of base salary, without any minimum bonus payment amount, minimum performance target achievement threshold required to be met before an AIP bonus is earned, or a maximum bonus payment amount. Performance-Based Restricted Stock Unit Plan Performance Plan Overview To align the interests of our employees, including our named executive officers, with the long-term operational objectives of the Company the Compensation and Human Resources Committee approved and adopted a new performance-based restricted stock unit performance plan under the 2019 Equity Plan (the “Performance Plan”), relating to the Company’s successful achievement of certain operational and financial goals established by the Board (the “Performance Objectives”) during the Performance Plan’s three-year term, ending December 31, 2023 (the “Performance Period”). Each eligible employee is granted a target award of unvested PSUs based on the total Performance Objectives as of the start of the Performance period (each, a “Target Award”). Performance Plan Eligibility Under the Performance Plan, a named executive officer (and any other Company employee participating in the Performance Plan) is granted a Target Award of unvested PSUs after she or he becomes eligible and is added to the Performance Plan. Individuals become eligible to participate in the Performance Plan after completing 90 days of continuous employment with the Company. Eligible employees (including named executive officers) are added to the Performance Plan and granted a Target Award of unvested PSUs as of the first trading day of the first fiscal quarter following the date they become eligible to participate in the Performance Plan. Each eligible employee’s Target Award is eligible to vest during the Performance Period upon the Company’s achievement of Performance Objectives, as explained below. Vesting of Target Awards Each Target Award is eligible to vest during the Performance Period based on the Company’s achievement of the Performance Objectives, subject to the award recipient’s continued service with the Company though the date the Compensation and Human Resources Committee certifies the relevant Performance Objective has been achieved. The exact number of shares issuable pursuant to the Performance Plan depends on the level of the Company’s performance against the Performance Objectives, and in general can range from 0% to 100% of the total Target Award. Unvested PSUs corresponding to Performance Objectives that have not been achieved as of the end of the Performance Period of the end of the employee’s service with the Company will be forfeited. 68 Under the Performance Plan, each Target Award is divided into two Performance Objectives: (i) the Infrastructure Development Target; and (ii) the Adjusted EBITDA Target. Infrastructure Development Target The “Infrastructure Development Target” relates to the Company’s successful development and monetization of up to 1,500 megawatts (“MW”) of Bitcoin mining and hosting infrastructure. The Infrastructure Development Target is further divided into fifteen 100 MW project units generally corresponding to one 100 MW Bitcoin mining structure owned and operated by the Company (each, a “Project Unit”). A Project Unit may only be achieved once, and only those Project Units which have not been achieved as of the date the employee is added to the Performance Plan. Each Project Unit consists of the following three milestone goals: 1. Installation of High-Voltage Energy Infrastructure . One-third of the Project Unit will vest upon the successful installation of the electricity transmission infrastructure interconnected to grid and capable of delivering usable power to the Bitcoin mining structure. 2. Development of Miner-Ready Infrastructure . One-third of the Project Unit will vest upon the successful development of a miner-ready building, which is deemed to occur when a Bitcoin mining structure has: (i) sufficient racking installed to house miners capable of utilizing the full usable electrical capacity of the building; (ii) highspeed internet and electrical power (including all of the medium and low voltage equipment necessary to deliver power to operating miners) connected to the racks; and (iii) the cooling system (air or immersion) installed and ready for operation. and 3. Monetization of Capacity . One-third of the Project Unit will vest upon the installation and operation of miners (whether the Company’s miners deployed in a self-mining capacity, or third-party miners installed in a hosted capacity) utilizing the full usable power capacity of the Miner-Ready Infrastructure installed at the Bitcoin mining structure. The Compensation and Human Resources Committee assesses the Company’s achievement of the Infrastructure Development Target (and thus, the vesting of PSUs allocated to the Project Units under the Infrastructure Development Target) on a quarterly basis, once results for the preceding fiscal quarter are available for the Compensation and Human Resources Committee’s review. Accordingly, the PSUs allocated to the portions of the Project Unit(s) achieved during the preceding fiscal quarter will vest upon on the Compensation and Human Resources Committee’s certification that such portions of the Project Unit(s) have been achieved, provided the award recipient remains employed by the Company through the date the Compensation and Human Resources Committee certifies such achievement. Adjusted EBITDA Target The “Adjusted EBITDA Target” relates to the Company’s achievement of financial performance objectives established by the Board based on increases in the Company’s annual Adjusted EBITDA (a non-GAAP financial measure used by the Board to assess performance). The Adjusted EBITDA Target is divided into ten $50 million Adjusted EBITDA milestones (i.e., up to $500 million in total added Adjusted EBITDA), each of which can only be achieved once during the Performance Period. The Compensation and Human Resources Committee assesses the Company’s achievement of Adjusted EBITDA milestones annually, and PSUs relating to the Adjusted EBITDA Target vest upon the Compensation and Human Resources Committee’s certification that an Adjusted EBITDA milestone has been achieved. Any unvested PSUs allocated to the Adjusted EBIDTA Target that are unvested as of the end of the Performance Period or the earlier end of the employee’s service with the Company will be forfeited. For more explanation of the Company’s use of Adjusted EBITDA, see the discussion of under the heading “Non-GAAP Measures” in the MD&A under Part II, Item 7 of this Annual Report. Change In Control Policy We believe that to properly motivate and incentivize our executive team in the event of a change in control and to the possibility of a termination without “cause” or a termination with “good reason,” a standardized “double trigger” change in control and severance policy is critical. We have agreed to provide payments and benefits to our named executive officers and certain other executive officers in the event of a termination without “cause” or by the officer for “good reason” following a change in control transaction. Our Compensation and Human Resources Committee approves all change in control compensation and periodically evaluates the appropriateness of such compensation in light of advice from the Board’s compensation advisers, Meridian, as well as the directors’ evaluation of the Company, its competitors, and the Bitcoin mining industry generally. We believe that these change in control benefits assist to maximize stockholder value and maintain our named executive officers’ focus in the period prior to, during and after the change in control event. 69 Clawback Policy We believe that it is important to foster and maintain a culture that emphasizes integrity and accountability. For this reason, we enter into executive employment agreements with our named executive officers that provide the Company with the ability to recover certain incentive compensation paid or payable to named executive officer under certain circumstances, such as a material restatement of all or a portion of our financial statements caused by or partially caused by the named executive officer’s misconduct (the “Clawback Policy”). The Clawback Policy generally permits us to require that any current or former named executive officer who is (or was) subject to Section 16 of the Exchange Act, repay certain cash-based incentive compensation or performance-based equity compensation to the Company if the Compensation and Human Resources Committee determines that such named executive officer’s misconduct actions caused or partially caused the Company to restate all or a portion of its financial statements within the applicable period from the original filing date of the restated financial statements. If the Compensation and Human Resources Committee determines that any such cash-based incentive compensation or performance-based equity compensation would have been less had they been calculated based on the restated results, and further determines that fraud, gross negligence, or intentional misconduct by any such named executive officer caused or partially caused such restatement, and that it is in our best interests to recover all or a portion of the excess amount of cash-based incentive compensation or performance-based equity compensation received (or to be received) by such named executive officer, the Compensation and Human Resources Committee may seek to recover the difference between the amounts awarded or paid (or to be awarded or paid) and the amounts that would have been awarded or paid based on the restated results. When the SEC adopts final clawback policy rules under the Dodd-Frank Wall Street Reform and Consumer Protection Act, we will review and may revise our Clawback Policy to the extent required to comply with such rules. Hedging and Pledging Policies We have established an Insider Trading Policy, which applies to all of our employees and directors, and, among other things, prohibits short sales, engaging in transactions in publicly-traded options (such as puts and calls) and other derivative securities relating to our common stock. This prohibition extends to any hedging or similar transaction designed to decrease the risks associated with holding our securities. In addition, our named executive officers are prohibited from pledging any of our securities as collateral for a loan and from holding any of our securities in a margin account. Tax and Accounting Considerations Accounting Treatment We recognize a non-cash charge to earnings for accounting purposes for equity awards. We expect that our Compensation and Human Resources Committee will continue to review and consider the accounting impact of equity awards in addition to considering the impact for dilution and overhang when deciding the amounts and terms of equity grants. Deductibility of Executive Compensation Code Section 162(m) may limit the amount that we may deduct from our federal income taxes for compensation paid to certain of our current or former executive officers who qualify as “covered employees” within the meaning of Code Section 162(m) to one million dollars per executive officer per year. While we are mindful of the benefit of the full deductibility of compensation, we believe that we should not be constrained by the requirements of Code Section 162(m) where those requirements would impair our flexibility in compensating our executive officers in a manner that can best promote our corporate objectives. Therefore, we have not adopted a policy that would require that all compensation be deductible, though we do consider the deductibility of compensation when making compensation decisions. We may authorize compensation payments that are not fully tax deductible if we believe that such payments are appropriate to attract and retain executive talent or meet other business objectives. 70 Taxation of Parachute Payments and Deferred Compensation We have no obligation to provide any executive officer, including any named executive officer, with a “gross-up” or other reimbursement payment for any tax liability that they might owe as a result of the application of Section 280G, 4999, or 409A of the Code, however, we may provide additional payments to cover taxes due in connection with the vesting and settlement of RSU and PSU awards, or otherwise provide for net settlement of vested RSUs and PSUs to cover the state and federal taxes due thereon, as permitted under the 2019 Equity Plan and approved by the Compensation and Human Resources Committee. Sections 280G and 4999 of the Code provide that executive officers and directors who hold significant equity interests and certain other service providers may be subject to an excise tax if they receive payments or benefits in connection with a change in control that exceed certain limits prescribed by the Code, and that the employer may forfeit a deduction on the amounts subject to this additional tax. Section 409A of the Code also may impose significant taxes on a service provider in the event that they receive deferred compensation that does not comply with the requirements of Section 409A of the Code. We have structured our compensation arrangements with the intention of complying with or otherwise being exempt from the requirements of Section 409A of the Code. Risk and Analysis of Compensation Plans The Compensation and Human Resources Committee engaged with Meridian to assess and determine whether the design and operation of our compensation policies and practices could encourage executives or employees to take excessive or inappropriate risks that would be reasonably likely to have a material adverse effect on our Company. In assessing our policies and practices, the following factors among others were analyzed: the design; size and scope of our cash and equity incentive programs and program features that mitigate against potential risks, such as payout caps, equity award clawbacks, the quality and mix of performance-based and “at risk” compensation; various policies such as trading, severance, and benefits, and governance. After reviewing the analysis performed by Meridian, we concluded that any potential risks arising from our employee compensation policies and practices, including our executive compensation programs, are not reasonably likely to have a material adverse effect on our company. Compensation and Human Resources Committee Report This report of the Compensation and Human Resources Committee is required by the SEC and, in accordance with the SEC’s rules, will not be deemed to be part of or incorporated by reference by any general statement incorporating by reference into any filing under the Securities Act or the Exchange Act, except to the extent that we specifically incorporate this information by reference, and will not otherwise be deemed “soliciting material” or “filed” under either the Securities Act or the Exchange Act.

Upon entry into his current executive employment agreement, Mr. McGonegal was granted an equity award of 20,000 RSUs under the Company’s 2019 Equity Plan, which are eligible to vest in four equal quarterly installments following his appointment as Chief Financial Officer, and which are convertible into shares of our common stock on a one-for-one basis following vesting. Any equity Mr. McGonegal may receive pursuant to his executive employment agreement will be awarded under the Company’s 2019 Equity Plan, as the same may be amended or replaced from time to time during the term of his employment as our Chief Financial Officer. During the fiscal year ended December 31, 2020, Mr. McGonegal served as our CEO and Chief Financial Officer pursuant to an executive employment agreement, dated as of February 2, 2020, at an annual base salary of $250,000, and was awarded 209,790 RSUs on February 7, 2020 under the Company’s 2019 Equity Plan.

During the initial three-year term of her employment as our Chief Operating Officer, Ms. Brooks was paid an annual base salary of $275,000 and was eligible to receive additional cash incentive bonuses, which was paid in accordance with the Company’s regular payroll practices as compensation for her services as Chief Operating Officer.

These RSUs are convertible into shares of our common stock on a one-for-one basis following vesting, in accordance with the terms of the equity award agreement. As additional compensation for her services as our Chief Operating Officer, Ms. Brooks was also eligible to receive periodic equity awards, which are subject to vesting schedules and other terms and conditions, as set forth in equity award agreements with the Company. Any equity Ms. Brooks received pursuant to her executive employment agreement were awarded under the Company’s 2019 Equity Plan. 79 Prior to her appointment on April 6, 2021 as our Chief Operating Officer, Ms. Brooks served as Riot’s Vice President of Finance, a position to which she had been appointed in fiscal year 2020, at an annual base salary of $175,000, and she received equity awards of 117,073 RSUs under the Company’s 2019 Equity Plan, pursuant to an equity award agreement with the Company, all of which were vested as of December 31, 2021. On March 21, 2022, we entered into a Separation and Release Agreement (the “Separation Agreement”) with our Chief Operating Officer, Ms. Brooks, regarding her separation from us, effective as of April 7, 2022 (the “Separation Date”), and her provision of certain transition services to us to help facilitate a smooth transition following the cessation of her employment with us from the Separation Date through July 7, 2022, unless earlier terminated as provided in the Separation Agreement (the “Transition Period”). Under applicable law, the Separation Agreement may be revoked for seven days following its execution; therefore, the Separation Agreement will become effective as of March 29, 2022, unless earlier revoked. The Separation Agreement provides for: (i) a customary waiver and release in favor of the Corporation; (ii) reconfirmation and certain extensions of the obligations under existing agreements pertaining to confidentiality and intellectual property ownership; (iii) the parties’ agreements regarding cooperation following the Separation Date; (iv) the provision of certain transition services to the Corporation and payment of the transition services fees; and (v) upon the Separation Agreement becoming binding and enforceable by its terms, payment of the following amounts as separation benefits: (A) a cash severance payment of $406,250.00, less amounts withheld for applicable taxes, representing 15 months’ base salary, payable in semi-monthly installments commencing July 7, 2022 according to Riot’s ordinary compensation practices; (B) a lump-sum payment as of the Separation Date of $86,370.00, less amounts withheld for applicable taxes, representing the pro-rated portion of the gross annual Incentive Bonus amount for fiscal year 2022 accrued through the Separation Date; (C) continued vesting through the end of the Transition Period of 6,000 time-based RSUs previously granted under the 2019 Equity Plan pursuant to the RSU award agreements dated as of April 7, 2021 and November 5, 2021, with acceleration of the final 1,500 RSUs awarded under the November 5, 2021 RSU award agreement as of July 7, 2022, as permitted under the 2019 Equity Plan and as approved by the Corporation’s Compensation and Human Resources Committee; (D) continued vesting through the end of the Transition Period of the performance-based PSUs previously granted under the 2019 Equity Plan pursuant to the PSU award agreement dated as of August 12, 2021, based on the Corporation’s performance as of the end of Q2 2022 on June 30, 2022; and (E) if continuing coverage under our group medical plan is elected pursuant to the Consolidated Omnibus Budget Reconciliation Act, as amended, (“COBRA”) payment of COBRA premiums until the earlier of 18 months after the Separation Date or the date such coverage commences under a subsequent employer’s medical insurance plan. Further, in consideration of the transition services, we agreed to pay a cash fee of $81,250.00, payable in semi-monthly installments throughout the Transition Period, and grant 75,000 RSUs under the 2019 Equity Plan, which are eligible to vest in three equal tranches as of May 7, 2022, June 7, 2022, and July 7, 2022. William R. Jackman, General Counsel Effective July 5, 2021, we entered into an executive employment agreement with Mr. Jackman, pursuant to which he has agreed to serve as our General Counsel for a three-year term, which renews for successive one-year terms after the expiration of the initial term. As our General Counsel, Mr. Jackman will receive a prorated annual base salary of $300,000 and is eligible to receive additional incentive bonuses under the AIP, which will be paid in accordance with the Company’s regular payroll practices as compensation for his services as our General Counsel. Mr. Jackman was also granted an equity award of 10,630 time-based RSUs under and pursuant to the 2019 Equity Plan, which are eligible to vest in four equal quarterly installments following his appointment as General Counsel. These RSUs are convertible into shares of our common stock on a one-for-one basis following vesting, in accordance with the terms of the applicable equity award agreement. As additional compensation for his services as our General Counsel, Mr. Jackman is also eligible to receive periodic grants of equity awards, including incentive compensation awards, which will be subject to vesting schedules and other terms and conditions, as set forth in equity award agreements with the Company, to be entered into as of the date of such future awards. Any equity Mr. Jackman may receive pursuant to his executive employment agreement will be awarded under the 2019 Equity Plan, as the same may be amended or replaced from time to time during the term of his employment as our General Counsel. Potential Payments Upon Termination or Change in Control The following table discloses the potential payments upon termination or change in control that would have been received by our named executive officers, had a termination event occurred on December 31, 2021 based on the terms of the applicable employment agreements and equity award agreements that were in effect on that date. The table assumes that any equity awards that vest in connection with the applicable triggering event that are subject to performance conditions are earned at the target level of performance within the applicable period except as may be noted otherwise, and values equity awards based on the closing price of a share of our common stock on December 31, 2021 of $22.33, as reported on the Nasdaq Capital Market. These amounts are estimates only and do not necessarily reflect the actual amounts that would be paid to the named executive officers, which amounts would only be known at the time that he or she becomes entitled to such payment. 80 Termination Event Named Executive Officer Termination For Cause or Without Good Reason Termination Without Cause or For Good Reason Death or Disability (2) Change in Control (Single Trigger) Change in Control (Double Trigger) (3) Benefit (1) ($) ($) ($) ($) ($) Jason Les, Chief Executive Officer Severance — 703,065 175,766 — 703,065 Restricted Stock Units — 6,444,818 — — 6,444,818 Options — — — — — Total — 7,147,882 — — 7,147,882 Jeffrey McGonegal, Chief Financial Officer Severance — 180,000 150,000 — 360,000 Restricted Stock Units — 111,650 891,075 — 111,650 Options — — — — — Total — 291,650 1,041,075 — 471,650 Megan Brooks, Chief Operating Officer (former) Severance — 325,000 81,250 — 325,000 Restricted Stock Units — 66,990 — — 66,990 Options — — — — — Total — 391,990 — — 391,990 Benjamin Yi, Executive Chairman Severance — 703,065 175,766 — 703,065 Restricted Stock Units — 5,083,246 — — 5,083,246 Options — — — — — Total — 5,786,310 — — 5,083,246 William Jackman, General Counsel Severance — 300,000 75,000 — 300,000 Restricted Stock Units — 118,684 — — 118,684 Options — — — — — Total — 418,684 — — 418,684 ___________________________________ (1) “Severance” excludes the cost of COBRA coverage, as well as the named executive officer’s AIP bonus, because the amount of the AIP target bonus granted to the named executive officer is contingent upon the future achievement of performance objectives that cannot be reasonably predicted; further, the named executive officer’s AIP performance target (i.e., the maximum percentage of the named executive officer’s base salary that can be achieved as an AIP bonus for the applicable year) is set each year by the Compensation and Human Resources Committee based on contemporaneous business expectations and conditions, which likewise cannot be reasonably predicted. “Restricted Stock Units” includes time-based restricted stock units (RSUs) granted under and subject to the terms and conditions of the 2019 Equity Plan but excludes performance-based restricted stock units (PSU) granted pursuant to the performance-based restricted stock unit plan established under the 2019 Equity Plan, because the amount and vesting of the PSU awards granted to the named executive officer are contingent upon the Company’s future achievement of performance objectives, the achievement of which cannot be reasonably predicted. (2) Assumes death or disability as of December 31, 2021 and maximum bonus payout. (3) We have a “Double-Trigger” Change in Control policy that applies to all compensation paid or payable to our named executive officers (and other employees), including any equity compensation paid or payable under the 2019 Equity Plan, which governs all of our currently outstanding equity awards. Accordingly, a Change in Control (as defined in the 2019 Equity Plan) does not automatically trigger any Severance, accelerated vesting of Restricted Stock Units or Options, or any other post-employment benefits without a subsequent qualifying separation from service, diminution in responsibilities, or other “Good Reason” termination event (as defined in the 2019 Equity Plan). If a Change in Control is followed by a subsequent qualifying separation from service with the period specified under our agreements with the named executive officer (generally six to twelve months following the Change in Control), the vesting of any unvested RSUs held by the named executive officer as of the Change in Control is automatically accelerated such that the unvested RSUs are deemed to have vested as of immediately prior to the consummation of the applicable Change in Control event. No severance is due to the named executive officer following a Change in Control unless a subsequent qualifying separation from service occurs. 81 Director Compensation We pay our non-employee directors a mix of cash and equity compensation, in amounts recommended by the Compensation and Human Resources Committee in consultation with independent compensation consultants the committee engages from time to time to assess the appropriateness of the Board’s compensation package. In recommending changes to the Company’s director compensation package, the Compensation and Human Resources Committee reviews market data provided by independent compensation consultants and considers whether any changes in director compensation are required to enable the Company to retain talented Board members, who, as members of the Board, are responsible for setting the Company’s strategic vision, overseeing its growth and development, and protecting its stockholders’ interests. Director Compensation Table The following table shows the total compensation paid or accrued during the year ended December 31, 2021 to each of our directors, current and former, for services as our director: Name Fees Earned or Paid in Cash Stock Awards (1) Option Awards Non-Equity Incentive Plan Compensation Non-Qualified Deferred Compensation Earnings Total (2) ($) ($) ($) ($) ($) ($) Benjamin Yi (3) — — — — — — Jason Les (4) — — — — — — Hubert Marleau (5) 57,000 498,250 — — — 555,250 Hannah Cho (6) 55,571 498,250 — — — 553,821 Lance D’Ambrosio (7) 38,129 339,125 — — — 377,254 (1) The “Stock Awards” column reflects the aggregate grant date fair value for RSU awards granted during the fiscal year ended December 31, 2021, computed in accordance with FASB ASC Topic 718. For details as to the assumptions used to determine the grant date fair value of RSU awards, see the information beginning on page F-39 in our Original Form 10-K under Note 13. Restricted Common Stock, Stock Options, Restricted Stock Units (“RSUs”) and Warrants, in the Notes to Consolidated Financial Statements of Riot Blockchain, Inc. and Subsidiaries included in Part II, Item 8. Financial Statements and Supplementary Data, of this Annual Report. (2) The amounts reflected on this table are computed in accordance with FASB ASC Topic 718 and therefore reflect the fair value of any stock awards as of the date of grant. According to ASC 718, fair value for these stock awards is recorded as the last reported trading piece of our securities on the Nasdaq Capital Market on the date of grant, without accounting for the effect of possible forfeitures. Stock awards are subject to fluctuations in the trading price of our securities while they remain unsettled; accordingly, the reported value of these Stock Awards may not reflect the actual value received by award recipients upon vesting and settlement. (3) On May 24, 2021, Mr. Yi was appointed as our Executive Chairman, making him an executive officer of the Company. Accordingly, commencing May 24, 2021, Mr. Yi no longer receives additional compensation for his services as a director on the Board.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS The following table sets forth certain information regarding the beneficial ownership of our Common Stock, as of March 31, 2022, for the following: ● each person or group of affiliated persons (as such term is used in Section 13(d)(3) of the Exchange Act) who we know to beneficially own five percent (5.00%) or more of the outstanding shares of our Common Stock; ● each of our directors; ● each of our named executive officers for the year ended December 31, 2021; and ● all of our directors and all of our named executive officers for the year ended December 31, 2021 as a group. We have based our calculation of the percentage of beneficial ownership on 117,304,304 shares of our Common Stock issued and outstanding as of March 31, 2022. We have determined beneficial ownership in accordance with applicable SEC rules and regulations, and thus it represents sole or shared voting or investment power with respect to our securities. Unless otherwise indicated below, to our knowledge, the persons named in the table have sole voting and sole investment power with respect to all shares that they beneficially owned, subject to community property laws where applicable. 83 Solely for the purpose of computing the number of shares of our Common Stock beneficially owned by a person and the percentage beneficial ownership of our securities of such person for this table in accordance with SEC rules, we have deemed shares underlying convertible securities and other equity rights, including RSUs and PSUs, that are vested and exercisable as of March 31, 2022, or are expected to become vested and exercisable within 60 days of March 31, 2022, to be outstanding and beneficially owned by the holder thereof as of March 31, 2022. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person. In accordance with Exchange Act Rule 13d-3, we have computed the shares deemed beneficially owned by such persons without regard for any net settlement for taxes or other withholdings permitted under the 2019 Equity Plan and approved by the Compensation and Human Resources Committee, and we have excluded from this calculation those shares underlying all outstanding convertible securities and equity rights, including RSUs and PSUs, which are subject to vesting which we do not expect to occur within 60 days of March 31, 2022. As explained under the heading “ Performance-Based Restricted Stock Unit Plan ” in Item 11 above, PSUs granted under the Performance Plan vest upon the Company’s achievement of Performance Objectives, which is tested following the end of each fiscal quarter during the Performance Period ending December 31, 2023.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE Related Person Transaction Policy The Audit Committee has responsibility for reviewing and, if appropriate, for approving any related party transactions that would be required to be disclosed pursuant to applicable SEC rules. This includes current or proposed transactions in which the Company was or is to be a participant in which the amount involved exceeds the lower of either $120,000 or 1% of the average of the Company’s total assets at year-end for the last two completed fiscal years, and in which any of the Company’s executive officers, Directors, or stockholders (or groups of stockholders) owning more than 5% of the Company’s outstanding common stock, or any immediate family members of such persons (collectively a “Related Party”), has a direct or indirect material interest. Our Audit Committee reviews and approves any transaction with a Related Party we propose to enter into. Our Audit Committee charter details the policies and procedures relating to transactions that may present actual, potential or perceived conflicts of interest and may raise questions as to whether such transactions are consistent with the best interest of our company and our stockholders. Such transactions will be entered into only if found to be in the best interest of the Company and approved in accordance with the Company’s Code of Ethics, which is available on the “Investors” page of Company’s website, www.riotblockchain.com , under the “Governance” tab. Since the beginning of the Company’s last fiscal year, no transactions with a Related Party were approved by the Audit Committee.
