Dear Stockholders:

You are cordially invited to attend the 2022 Annual General Meeting of the stockholders (the “Annual Meeting”) of Riot Blockchain, Inc. (“Riot” or the “Company”) to be held at 9:00 a.m. (Eastern Time) on Wednesday, July 27, 2022, via the virtual meeting portal at:

www.virtualstockholdermeeting.com/RIOT2022

Due to the ongoing effects of the global coronavirus (COVID-19) pandemic and emerging variants of the coronavirus across North America and around the world, we continue to have heightened awareness and appreciation for our diverse and international network of stockholders who may be affected by attending the Annual Meeting in person. After careful consideration of potential travel disruptions and the availability of accommodations, and in light of public safety concerns, the Board of Directors of the Company (the “Board”) has determined to host the Annual Meeting entirely online via the virtual meeting portal. As such, no in-person attendance option will be available for the Annual Meeting. We believe our stockholders should have the ability to attend the Annual Meeting, regardless of where they live; and, especially in light of the ongoing global COVID-19 pandemic, we believe the virtual format of this year’s Annual Meeting will better enable stockholder attendance and enhance stockholder experience at the meeting.

The attached Notice of 2022 Annual General Meeting of Stockholders (the “Notice”) and the accompanying Proxy Statement describe the matters to be presented at the Annual Meeting and provide information about Riot that you should consider when you vote your shares. Copies of the Notice and the Proxy Statement have been filed with the U.S. Securities and Exchange Commission (the “SEC”) and can be obtained from the SEC’s website, www.SEC.gov.

The principal business of the Annual Meeting, as described in greater detail in the Proxy Statement, will be to conduct a stockholder vote on the following five (5) proposals:

In addition, we will transact such other business as may be properly brought before the Annual Meeting and any adjournments or postponements thereof.

After careful deliberation of each of these proposals, the Board unanimously recommends that you vote your shares at the Annual Meeting as follows:

Only stockholders as of the close of business on Tuesday, May 31, 2022 (the “Record Date”), are entitled to receive notice of and vote at the Annual Meeting and any postponement or adjournment thereof. If you are a stockholder as of the Record Date, you will be able to register for, participate in, vote your shares electronically, and submit your questions during the live webcast of the Annual Meeting by visiting the virtual meeting portal www.virtualstockholdermeeting.com/RIOT2022 and entering the unique 16-digit control number assigned to you, which can be found on the enclosed proxy card and voting instruction form.

The Board of Directors have established the close of business on Tuesday, May 31, 2022, as the record date (the “Record Date”) for determining those of our stockholders entitled to attend and to vote their shares at the Annual Meeting. Accordingly, only holders of our common stock, no par value per share, of record at the close of business on the Record Date will receive this Notice and be eligible to attend and vote their shares at, the Annual Meeting (including any adjournment or postponement thereof). Holders of other classes of our outstanding capital stock are not entitled to participate in the Annual Meeting. As of the Record Date, there were 135,347,900 shares of common stock, no par value per share, outstanding entitled to vote at the Annual Meeting. The foregoing shares of our common stock, no par value per share, are referred to herein as the “shares.” A list of stockholders of record will be available at the Annual Meeting online at the virtual meeting portal, www.virtualstockholdermeeting.com/RIOT2022, and will be available by request during the ten (10) days prior to the Annual Meeting by submitting your written request to our Corporate Secretary at Riot Blockchain, Inc., 3855 Ambrosia Street, Suite 301, Castle Rock, Colorado 80109, Attention: Corporate Secretary.

Your vote is important. Whether or not you plan to attend the virtual Annual Meeting live, we encourage you to please read the accompanying Proxy Statement and vote your shares by proxy as soon as possible so that we can ensure your vote will be represented at the Annual Meeting.

You may submit your vote by proxy using any of the following methods:

Your proxy, whether given online at www.proxyvote.com or through the return of the enclosed proxy card, may be revoked prior to its exercise by writing to: Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717 and by filing a written notice of revocation or a duly executed proxy bearing a later date with our Corporate Secretary prior to the Annual Meeting, or by attending the Annual Meeting and voting virtually using your 16-digit control number and entering the virtual meeting portal at www.virtualstockholdermeeting.com/RIOT2022. To ensure fair conduct of the Annual Meeting and that our stockholders of record are able to participate in the Annual Meeting, you will not be able to participate in the virtual Annual Meeting without the unique 16-digit control number assigned to you and provided on the back of your proxy card.

We urge you to review the accompanying materials carefully and to vote as promptly as possible. Please note that we have enclosed the Proxy Statement and your proxy card along with this Notice.

Castle Rock, CO

June 17, 2022

 

We include these questions and answers to provide some background and clarity concerning voting, solicitation and other general information. We encourage you to read this Proxy Statement carefully and in its entirety.

We sent you this Proxy Statement or a Notice of Internet Availability of Proxy Materials in connection with the solicitation by our Board of Directors (the “Board”) of your proxy to vote at the Company’s Annual Meeting (including any adjournments or postponements thereof).

This Proxy Statement summarizes the information you need to know to vote on an informed basis. It contains information relating to the proposals to be voted on at the Annual Meeting, the voting process, the compensation of our directors and most highly paid executive officers, and other required information.

The purpose of the Annual Meeting is to obtain stockholder action on the matters outlined in the Notice included with this Proxy Statement. These matters include:

This Proxy Statement provides detailed information about each of these matters.

You may vote if you are a stockholder of our common stock, no par value per share, at the close of business on Tuesday, May 31, 2022 (the “Record Date”), as identified by our transfer agent. As of the Record Date, there were 135,347,900 shares issued, outstanding and entitled to vote at the Annual Meeting. Shares of our common stock, no par value per share, are herein referred to as the “shares.”

Each stockholder of record is entitled to one vote at the Annual Meeting for each share of common stock owned as of the Record Date. Cumulative voting is not permitted.

Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy. If your proxy is properly submitted, you are legally designating the person or persons named on the proxy card to vote your shares as you have directed. All valid proxies that we receive through this solicitation, which are not revoked, will be voted in accordance with instructions you provide on the proxy card. Except as set forth below, if you properly submit a proxy without giving specific voting instructions, your shares will be voted in accordance with the Board’s recommendations as noted above. Voting by proxy will not affect your right to attend the Annual Meeting.

How you may vote depends on how your shares are held. As explained below, the voting procedures are different for stockholders of record and for beneficial owners of our shares.

Many of our stockholders hold their shares through stock brokers, banks, or other nominees, rather than directly in their own names. As summarized below, there are some differences between being a stockholder of record and a beneficial owner.

Stockholder of Record. If your shares are registered directly in your name with our transfer agent, Equiniti Trust Corporation, or if you possess stock certificates representing your shares, you are the stockholder of record, and these proxy materials are being sent directly to you. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals named on the proxy card or to vote at the Annual Meeting. If you are a stockholder of record, you may vote your shares at the Annual Meeting using any of the following methods:

Beneficial Owners. If your shares are held in a stock brokerage account or by a bank or other nominee, you are the beneficial owner of shares held in “street name”. Your proxy materials are being forwarded to you by your broker or other nominee, who is considered to be the stockholder of record. As the beneficial owner, you have the right to tell your nominee how to vote, and you are also invited to attend the Annual Meeting virtually. However, since you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you obtain a legal proxy from your nominee authorizing you to do so. Your nominee has sent you instructions on how to direct the nominee’s vote. You may vote by following those instructions and the instructions on the Notice; and, if you are a beneficial owner, who obtained a legal proxy and is authorized to vote by your nominee, and you wish to submit your vote by telephone, you may do so by dialing 1-800-454-8683.

You do not need to attend the Annual Meeting to vote your shares. Shares represented by valid proxies that are received in time for the Annual Meeting will be voted at the Annual Meeting unless they are revoked in advance of the meeting date. A stockholder may revoke a proxy before the proxy is voted by following the instructions under the heading “May I change or revoke my proxy?” below. Any stockholder who has executed a proxy card but attends the Annual Meeting via the virtual meeting portal at www.virtualstockholdermeeting.com/RIOT2022 may revoke the proxy and vote at the Annual Meeting by following the instructions under the heading “How do I vote?” above.

A proxy is your legal designation of authority to another person (your proxy) to vote the shares you own. If you designate someone as your proxy, the document in which you make that designation also is called a proxy.

If you submit your proxy, you may alter or revoke your proxy at any time prior to the Annual Meeting. You may alter or revoke your proxy in any one of the following ways:

You may receive more than one proxy card or voting instruction form if you hold shares of our common stock in more than one account, which may be in registered form or held in street name. Please vote in the manner described under “How do I vote?” on the proxy card for each account to ensure that all your shares are voted.

If shares are registered in your name, they will not be voted if you do not submit your proxy card by mail, online via the portal at www.proxyvote.com, or by telephone by dialing 1-800-690-6903, or if you do not otherwise vote by attending the Annual Meeting and casting your shares using the unique 16-digit control number assigned to you on your Proxy Card. Please see the section of this Proxy Statement entitled “How do I vote?” beginning on page 2 above for specific instructions on how to vote your shares. Unless otherwise indicated under the section “What vote is required to approve each proposal presented at the Annual Meeting” below, if you submit your proxy card without identifying instructions as to how your shares should be voted, those shares will be voted in accordance with the Board’s recommendations, as permitted by the Company’s Bylaws.

Brokers who do not receive voting instructions from their clients have the discretion to vote uninstructed shares on certain matters (“routine matters”), but do not have the discretion to vote uninstructed shares as to certain other matters (“non-routine matters”). Of the five (5) proposals being presented to the stockholders at the Annual Meeting, Proposal No. 2 (the ratification of our independent registered public accounting firm) and Proposal No. 4 (vote to approve the amendment to the Company’s Articles of Incorporation) are considered routine matters. The remaining three (3) proposals, Proposal No. 1 (election of directors), Proposal No. 3 (advisory vote to approve the compensation of our named executive officers), and Proposal No. 5 (vote to approve the Third Amendment to the 2019 Riot Blockchain, Inc. Equity Incentive Plan) are each considered non-routine matters. This means that if your shares are held in street name and you do not provide voting instructions to the bank, broker or other nominee that holds your shares as described above under “How Do I Vote?,” the bank, broker or other nominee has the authority, even if it does not receive instructions from you, to vote your unvoted shares for the routine matters being presented to the stockholders at the Annual Meeting, Proposal No. 2 (the ratification of our independent registered public accounting firm) and Proposal No. 4 (vote to approve the amendment to the Company’s Articles of Incorporation). However, your bank, broker or other nominee that holds your shares would not have authority to vote the unvoted shares for the three (3) non-routine matters being presented to the stockholders at the Annual Meeting, Proposal No. 1 (election of director), Proposal No. 3 (advisory vote to approve the compensation of our named executive officers), and Proposal No. 5 (vote to approve the Third Amendment to the 2019 Riot Blockchain, Inc. Equity Incentive Plan).

If your broker cannot vote your shares on a particular matter because it has not received instructions from you and does not have discretionary voting authority on that matter, or if your broker chooses not to vote on a matter for which it does have discretionary voting authority, a “broker non-vote” has occurred. The effects of a broker non-vote on each of the proposals for which we are requesting stockholder votes are explained below.

Shares that are subject to a broker non-vote are considered present at the Annual Meeting for determining whether the quorum requirement has been met (see “What is a quorum?” on page 6 of this Proxy Statement for further discussion of our quorum requirement for the Annual Meeting); however, shares subject to a broker non-vote will not be counted as a vote cast with respect to a proposal. Because abstentions and broker non-votes do not represent shares cast with respect to a proposal, broker non-votes will have no effect on the outcome of votes on any of the proposals put forth in this Proxy Statement, except, as required under Nevada law and identified in this Proxy Statement, as the outcome of the votes on these proposals are determined solely by reference to the votes cast by the shares entitled to vote that are present at the Annual Meeting or represented by a properly-submitted proxy.

We encourage you to provide voting instructions. This ensures your shares will be voted at the Annual Meeting in the manner you desire.

Proposal No. 1: Election of Director. We are seeking stockholder votes on the election to the Board of one Class I director nominee as identified in this Proxy Statement. As permitted by Nevada law and our Bylaws, classes of directors on our Board are elected by a plurality voting system. This means that those director nominees receiving the most “FOR” votes cast in favor of their election to the Board will be elected to the Board.

You may vote “FOR” the nominee, or you may “WITHHOLD” your vote from the nominee. Votes that are withheld will not be included in the vote tally for the election of the director and thus will have no effect on the outcome of the vote on this proposal. If you submit your proxy card without directing your proxy how to vote your shares, your shares will be voted in accordance with the Board’s recommendations.

Brokerage firms do not have authority to vote customers’ unvoted shares, held by the firms in street name, for the election of directors. As a result, any shares not voted by a beneficial owner will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote.

Proposal No. 2: Ratification of Auditor Appointment. We are seeking our stockholders’ ratification, in a non-binding vote, of our appointment of Marcum LLP to serve as our independent registered public accounting firm (our “Auditor”) for the fiscal year ending December 31, 2022. The ratification of the appointment of Marcum LLP as our Auditor for these periods requires the affirmative vote of the majority of the shares cast on this Proposal No. 2 (i.e., the number of “FOR” votes cast must exceed the number of “AGAINST” votes cast on this Proposal No. 2 to ratify our appointment of Marcum LLP as our Auditor). Under applicable Nasdaq market rules, Nevada law and SEC regulations, we are not required to obtain the approval of our stockholders to appoint our auditors.

Brokerage firms have authority to vote customers’ unvoted shares, held by the firms in street name, on this routine proposal. If a broker does not exercise this authority, a broker non-vote will result. Broker non-votes and abstentions will not be counted as votes cast and will have no effect on the outcome of the vote.

Proposal No. 3: “Say-On-Pay.” We are seeking an advisory vote by our stockholders regarding the compensation of our named executive officers, which is discussed in greater detail in this Proxy Statement. The affirmative vote of the majority of the shares cast on this Proposal No. 3 is required to approve, on a non-binding, advisory basis, the compensation of our named executive officers (i.e., the number of “FOR” votes cast must exceed the number of “AGAINST” votes cast on this Proposal No. 3 for stockholder advisory approval of the compensation of our named executive officers to be obtained). While the results of this advisory vote are non-binding, the Compensation and Human Resources Committee of the Board (the “Compensation Committee”), and the Board as a whole, values the opinions of our stockholders and will consider the outcome of the vote, along with other relevant factors, in deciding whether any actions are necessary to address the concerns raised by the vote and when making future compensation decisions for our named executive officers.

Brokerage firms do not have authority to vote customers’ unvoted shares, held by the firms in street name, for this proposal. As a result, any shares not voted by a beneficial owner will be treated as a broker non-vote. Broker non-votes and abstentions will not be counted as votes cast and will have no effect on the outcome of the vote.

Proposal No. 4: Approval to Amend the Company’s Articles of Incorporation. We are seeking stockholder approval to amend our Riot Blockchain, Inc. Articles of Incorporation. Amending the Articles of Incorporation will provide us the opportunity to increase the number of authorized shares of our common stock. The affirmative vote of a majority of the total number of shares of our common stock outstanding and entitled to vote as of the Record Date is required to approve the amendment to the Company’s Articles of Incorporation.

Brokerage firms have authority to vote customers’ unvoted shares, held by the firms in street name, on this routine proposal. If a broker does not exercise this authority, a broker non-vote will result. Abstentions and broker non-votes will have the same effect as a vote against this proposal.

Proposal No. 5: Approval of the Third Amendment to the Riot Blockchain, Inc. 2019 Equity Incentive Plan. We are seeking stockholder approval of an amendment to our Riot Blockchain, Inc. 2019 Equity Plan (the “2019 Equity Plan”), as amended to increase the number of shares of our common stock reserved for issuance under the 2019 Equity Plan by 10,000,000 shares. The affirmative vote of a majority of the votes cast for this proposal is required to approve the Third Amendment to the Riot Blockchain, Inc. 2019 Equity Plan (i.e., the number of “FOR” votes cast on this Proposal No. 5 must exceed the number of “AGAINST” votes cast on this Proposal No. 5 for stockholder approval of the amendment to the 2019 Equity Plan to be obtained).

Brokerage firms do not have authority to vote customers’ unvoted shares held by the firms in street name for this proposal. As a result, any shares not voted by a beneficial owner will be treated as a broker non-vote. Broker non-votes and abstentions will not be counted as votes cast and will have no effect on the outcome of the vote.

The Board unanimously recommends that you vote as follows:

If any other matter is presented, the proxy card provides that your shares will be voted by the proxy holder listed on the proxy card in accordance with his or her best judgment. At the time this Proxy Statement was printed, we knew of no matters that needed to be acted on at the Annual Meeting, other than those discussed in this Proxy Statement.

A quorum is the minimum number of shares that must be present at the Annual Meeting to properly hold an annual meeting and conduct business under our Bylaws and Nevada law. The attendance, virtually or by proxy, of holders of thirty-three and one third percent (33.333%) of the total shares outstanding as of the Record Date will constitute a quorum for doing business at the Annual Meeting. Therefore, based on 135,347,900 shares outstanding as of May 31, 2022, the presence of 45,115,516 shares, whether represented by their holder virtually or by proxy, will constitute a quorum for purposes of the Annual Meeting. If you grant your proxy and do not revoke it prior to the Annual Meeting, your shares will be considered present at the Annual Meeting and be counted toward the quorum. Proxies marked “Withhold” or “Abstain” and broker non-votes will be treated as shares that are present for purposes of determining whether a quorum has been met.

If the shares present virtually or represented by proxy at the Annual Meeting are not sufficient to constitute a quorum, the stockholders, by a vote of the holders of a majority of votes present virtually or represented by proxy (which may be voted by the proxy holders), may, without further notice to any stockholder (unless a new Record Date is set), adjourn the Annual Meeting to a different time and place to permit further solicitations of proxies sufficient to constitute a quorum.

The SEC has adopted a rule concerning the delivery of annual disclosure documents to households with more than one stockholder. The rule permits the Company or brokers holding Company shares on your behalf to send a single set of our Annual Report and Proxy Statement to any household at which two or more of our stockholders reside, if the stockholders appear to be members of the same family. Each stockholder will continue to receive a separate proxy card or voting instruction card. This procedure is referred to as “householding” and benefits both stockholders and the Company. Householding reduces the volume of duplicate information received by stockholders and helps to reduce our expenses. This rule applies to our Annual Reports, Proxy Statements and any information statements. Once stockholders receive notice that communications to their addresses will be “householded”, the practice will continue until stockholders are notified otherwise or until they revoke their consent to the practice.

If at any time a stockholder no longer wishes to participate in householding and would prefer to receive separate sets of our annual disclosure documents or Proxy Statement, they may revoke their consent for future mailings by contacting our proxy advisors and virtual webcast hosts for the Annual Meeting, Broadridge Financial Solutions, Inc. via:

Similarly, if an address is shared with another stockholder and, together, both stockholders would like to receive only a single set of our annual disclosure documents, the stockholders should follow the instructions above.

The Company will bear the cost of the solicitation of proxies; however, we will not pay our directors, officers and employees any additional compensation for soliciting proxies in person, by telephone or by other means. We may reimburse brokerage firms, banks and other agents for reasonable out-of-pocket expenses for forwarding proxy materials to beneficial owners. We have engaged Alliance Advisors, LLC, a proxy solicitation firm whose toll-free number is 1-866-620-9211, to assist us in soliciting proxies in connection with the Annual Meeting for an engagement fee of approximately $8,000, plus reimbursement of reasonable out-of-pocket expenses. Other proxy solicitation expenses that we will pay include those for preparing, mailing, returning, and tabulating the proxies.

We expect to announce preliminary voting results at the Annual Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Current Report on Form 8-K within four business days after the Annual Meeting, we will file a Current Report on Form 8-K to publish preliminary results and will provide the final results in an amendment to the Current Report on Form 8-K as soon as they become available.

All stockholder proposals, including stockholder proposals for candidates for nomination for election to the Board, should be submitted in accordance with applicable SEC rules and regulations, Nevada law, and the Company’s procedures for stockholder proposals, as described herein and under the heading “Communications with the Board” on page 16 of this Proxy Statement below. Stockholder proposals should be submitted to our Corporate Secretary by mail to the following address:

Riot Blockchain, Inc.

Stockholder proposals intended to be presented at, and included in the definitive proxy statement for, the 2023 Annual General Meeting of Stockholders (the “2023 Annual Meeting”) must be delivered to our Corporate Secretary on or before the close of business on February 17, 2023, to be considered timely pursuant to SEC Rule 14a-8 and our Bylaws. Stockholder proposals intended to be presented at the 2023 Annual Meeting outside of the SEC Rule 14a-8 process must be delivered to our Corporate Secretary at the above address no sooner than April 3, 2023, and no later than May 3, 2023, to be considered timely.

If the date of our 2023 Annual Meeting has been changed by more than thirty (30) days before or more than sixty (60) days after the first anniversary of this year’s Annual Meeting, stockholders must comply with the following procedure to submit their proposals to be considered at the 2023 Annual Meeting. If public announcement of the 2023 Annual Meeting occurs one hundred (100) days or more prior to the scheduled date of the 2023 Annual Meeting, then stockholder proposals must be delivered to our Corporate Secretary at the foregoing address no more than one hundred twenty (120) days before and no less than ninety (90) days before the date of the 2023 Annual Meeting to be considered at the meeting. However, if public announcement of the 2023 Annual Meeting occurs less than hundred (100) days prior to the scheduled date of the 2023 Annual Meeting, then stockholder proposals can be delivered up to ten (10) days after public announcement of the 2023 Annual Meeting is first made.

Stockholders may nominate candidates for the Board by the same deadlines as stockholder proposals for business to come before the 2023 Annual Meeting. Each notice of business or nomination must set forth the information required by our Bylaws. Any such proposals, including stockholder proposals for candidates for nomination for election to the Board, must be submitted in accordance with applicable SEC rules and regulations, and follow the Company’s procedures in its Bylaws. In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules (once effective), stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by SEC Rule 14a-19 no later than May 28, 2023. Submitting a notice does not ensure that the proposal will be raised at the 2023 Annual Meeting. We will not permit stockholder proposals or nominations that do not comply with the foregoing notice requirement to be brought before the 2023 Annual Meeting.

Benjamin Yi, age 40, has served as a director on the Company’s Board since 2018 and as its Chair since November 2020. 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. Yi has previously served as a member of each of the Board’s three standing committees, however, as of May 24, 2021, upon his appointment as the Company’s Executive Chairman, Mr. Yi resigned from his positions on the Audit Committee (including from his position as its chair), the Compensation and Human Resources Committee, and the Governance and Nominating Committee. As Executive Chairman, Mr. Yi continues to be a director on the Board, where he plays an integral role in establishing the Board’s strategic vision for the Company and, except when the Company’s bylaws, the Nasdaq Rules, the rules and regulations of the SEC, or Nevada law require him to abstain from the meeting, serve as Board chair.

In addition to his significant experience as a member of our Board and as one of our executive officers, Mr. Yi brings significant corporate governance experience to Riot’s Board, having served as an independent director and committee chair of several private and public companies. Prior to joining Riot’s Board in 2018, Mr. Yi served as an Independent Director and Chair of the Corporate Governance and Remuneration Committee of PetroMaroc Corporation, plc (formerly TSX-V: PMA), a Toronto-based energy company, from December 2013 to December 2016; as a member of the Board of Managers and Audit Committee of Android Industries, LLC, a privately held Michigan-based assembler of complex modules for the automotive industry, from January 2014 to September 2016; and as an Independent Director, member, and occasional Chair of the Audit Committee of Woulfe Mining Corp. (formerly CSE: WUF), a Vancouver-based mining company, from October 2013 to its acquisition in September 2015.

Mr. Yi also brings over fifteen years of unique capital markets experience to the Company, and a particular expertise in fintech, specialty finance, and investing throughout a company’s capital structure. Prior to his appointment as our Executive Chairman, Mr. Yi headed the capital markets and corporate development efforts at IOU Financial Inc. (TSX-V: IOU; OCTMKTS: IOUFF), a Montreal-based fintech-enabled lender to small businesses across North America. Previously, Mr. Yi worked directly under Ned Goodman, a renowned Canadian financier, investor, and founder of Dundee Corporation (TSE: DC.A; OCTMKTS: DDEJF), a Toronto-based conglomerated investment and corporate development company focused on the mining sector. At Dundee Corporation, he worked in a corporate development and investment capacity, investing throughout the capital structure of companies involved in the natural resource extraction, energy technology, real estate, and automotive sectors. Prior to Dundee Corporation, Mr. Yi was a securities analyst at the predecessor to 1832 Asset Management L.P., where he covered energy and special situations investments as part of a team managing one of North America’s largest natural resources-focused investment funds.

Mr. Yi is a CFA charter holder, and he holds a Master of Finance degree from the University of Toronto Rotman School of Management and a Bachelor of Commerce degree from Trinity College in University of Toronto.

We believe Mr. Yi is qualified to serve as a director on Riot’s Board based on his knowledge of the Company, his service as a member of its Board of Directors since 2018, his past service as chair of the Audit Committee and the Compensation and Human Resources Committee, and because he brings over fifteen years of dedicated financial markets experience to the Company. Mr. Yi leverages his expertise in capital markets and corporate development as a Board member to help shape Board discussions and strategic policymaking decisions as it seeks to continue to establish, oversee and improve Company policies designed to drive the growth of the Company and protect stockholder interests. Further, as a member of the Company’s executive team, Mr. Yi applies his expertise to assist the Company in carrying out the Board’s strategic vision.

Jason Les, age 36, has served as a director on the Company’s Board since November 2017 and, effective February 8, 2021, was appointed to serve as the Company’s Chief Executive Officer. Prior to his appointment as Chief Executive Officer, Mr. Les had served as a member of each of the Board’s three standing committees, including as chair of the Compensation and Human Resources Committee.

Mr. Les is the driving force behind the Company’s mission to become one of the most relevant and significant companies supporting the Bitcoin network. He has been deeply involved with Bitcoin since 2013, with significant experience in cryptocurrency mining, as an engineer studying protocol development, and contributing to open-source projects. He was also a founding partner of Binary Digital, a software-development company where he led the engineering team and coordinated project development for artificial intelligence, reverse engineering, and inter-software compatibility projects. Additionally, his background includes over a decade of unique experience as a former professional heads-up poker player, during which he has successfully competed in high-stakes games online, in addition to the most prestigious, high-stakes tournaments in the world. In 2015 and 2017, he was selected as a human benchmark for testing the world’s best poker artificial intelligence in what was dubbed “Man vs Machine” at Carnegie Mellon University. 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.

Hannah Cho, age 44, has served as a director on the Company’s Board, including as a member of each of its three standing committees, since February 2021. Ms. Cho currently serves as chair of the Compensation and Human Resources Committee. The Board has affirmatively determined that Ms. Cho meets the director independence standards of the Nasdaq Rules and the SEC, including the enhanced standards required for members of the Audit Committee and the Compensation and Human Resources Committee.

Ms. Cho is a veteran marketing and communications professional with a career of over fifteen years in the enterprise technology industry. She brings significant executive leadership experience in the enterprise technology brand marketing, product and corporate communications fields, which she gained at leading technology companies including Anaplan, CA Technologies, Intel Corporation, and Cisco Systems.

We believe Ms. Cho is qualified to serve as a director on Riot’s Board based on her extensive experience in the enterprise technology industry, and because she is able to bring her significant knowledge and expertise in the marketing and communications aspects of the enterprise technology space to bear to help the Board establish policies and strategies to assist the Company in navigating the public discourse regarding the Bitcoin mining industry.

Ms. Cho leverages her executive leadership experience, as well as her marketing and communications expertise in the enterprise technology space during Board discussions and strategic policymaking decisions to assist the Board as it seeks to continue to establish, oversee and improve Company policies designed to drive the growth of the Company and protect stockholder interests.

Lance D’Ambrosio, 65, has served as a director on the Company’s Board, including as a member of each of its three standing committees, since May 2021. Mr. D’Ambrosio currently serves as the chair of the Audit Committee. The Board has affirmatively determined that Mr. D’Ambrosio meets the director independence standards of the Nasdaq Rules and the SEC, including the enhanced standards required for members of the Audit Committee and the Compensation and Human Resources Committee. Further, based on his experience and financial expertise described below, the Board has determined that Mr. D’Ambrosio qualifies as an “audit committee financial expert” (as that term is defined in Item 407(d) of Regulation S-K) and has designated him as one of two audit committee financial experts presently serving on the Audit Committee.

Mr. D’Ambrosio has over thirty years’ experience as a corporate officer and director, including in corporate governance, capital raising, financial analysis, mergers and acquisitions, and complex international structuring. Mr. D’Ambrosio currently serves as the Managing Partner of 4 D Investments, a company which focuses on technology and real estate investments.

As a corporate executive, Mr. D’Ambrosio has founded and grown numerous companies spanning several industries including the telecommunications, materials, and automotive sectors. Over the course of his career, he has led capital raising efforts totaling hundreds of millions of dollars, executed on over thirty corporate acquisitions, successfully taken a number of companies public on both U.S. and international exchanges, and successfully sold several businesses to larger market participants, including Sprint Telecommunications and Comsat International, a subsidiary of Lockheed Martin.

He also has significant experience as an entrepreneur, having founded several companies spanning a broad spectrum of industries, including the telecommunications, materials, and automotive sectors.

We believe Mr. D’Ambrosio is qualified to serve as a director on Riot’s Board based on his extensive experience as a corporate executive, entrepreneur, and board member. He is able to leverage his substantial corporate governance and finance experience during Board discussions and strategic policymaking decisions to help the Board establish, oversee and improve Company policies designed to drive growth of the Company and protect stockholder interests.

Hubert Marleau, age 78, has served on our Board since November 2020 and currently serves as the Board’s Lead Independent Director and Chair of the Board’s Governance and Nominating Committee. As the Board’s Lead Independent Director, Mr. Marleau chairs those Board meetings from which our Executive Chairman, Mr. Benjamin Yi, is required to abstain from the meeting under the Company’s bylaws, the applicable rules and regulations of the Nasdaq Rules, the rules and regulations of the SEC, or Nevada law, as applicable. The Board has affirmatively determined that Mr. Marleau meets the director independence standards of the Nasdaq Rules and the SEC, including the enhanced standards required for members of the Audit Committee and the Compensation and Human Resources Committee. Further, based on his experience and financial expertise described below, the Board has determined that Mr. Marleau qualifies as an “audit committee financial expert” (as that term is defined in Item 407(d) of Regulation S-K) and has designated him as one of two audit committee financial experts presently serving on the Audit Committee.

Mr. Marleau is a veteran capital markets professional, corporate director, and Chair of the Marleau Lecture Series on Economic and Monetary Policy at the University of Ottawa. Mr. Marleau’s broad areas of expertise include macroeconomic policy & analysis, corporate governance, financial analysis, and investment banking, having served on the board of directors for more than fifty U.S. and Canadian publicly traded companies throughout his career.

Presently, Mr. Marleau serves as a member of the board of directors of Niocan, Inc. (TSX-V: NIO; OCTMKTS: NIOCF), a Montreal, Canada-based metals and minerals mining company, and of Premier Health of America Inc. (TSX-V: PHA), a Blainville, Québec-based specialized healthcare staffing and outsourcing services company, where he serves as president of its audit committee.

Mr. Marleau also has extensive capital markets experience, having raised funds privately and publicly for hundreds of emerging and mature companies, structured numerous mergers and acquisitions, and acted as the driving force behind numerous transactions throughout his career.

Mr. Marleau holds an Honours Bachelor of Social Sciences in Economics from the University of Ottawa.

We believe Mr. Marleau is qualified to serve as a director on Riot’s Board based on his extensive corporate governance and public company board experience, and because he brings over five decades of dedicated financial markets and economics experience to the Company. He brings his extensive experience and expertise to Board discussions and policymaking decisions, helping to assist the Board shape its strategic vision for the Company and as it seeks to continue to establish, oversee and improve Company policies designed to drive the growth of the Company and protect stockholder interests.

There are no familial relationships between any of the director nominees or our executive officers, nor are any of our directors, director nominees or executive officers party to any legal proceedings adverse to us.

The matrix below summarizes certain of the key experiences, qualifications, skills, and attributes that our director nominees bring to the Board to enable effective oversight. This matrix is intended to provide a summary of our director nominees’ qualifications and is not a complete list of each director nominee’s strengths or contributions to the Board. Additional details on each director nominee’s experiences, qualifications, skills, and attributes are set forth in their biographies above.

Our Corporate Governance Guidelines, together with our Board committee charters, provide the framework for the corporate governance of the Company. This promotes the interests of our stockholders and strengthens our Board and management accountability. Below is a summary of our Corporate Governance Guidelines and Board Committee Charters.

Our Code of Ethics and Business Conduct (the “Code of Ethics”) applies to our employees, directors, officers, contractors, consultants, and persons performing similar functions (“Covered Persons”). This includes our Principal Executive Officer and our Principal Financial Officer. We require that they avoid conflicts of interest, comply with applicable laws, protect our assets, and conduct business in an ethical and responsible manner and in accordance with the Code of Ethics. The Code of Ethics prohibits employees from taking unfair advantage of our business partners, competitors, and employees through manipulation, concealment, misuse of confidential or privileged information, misrepresentation of material facts, or any other practice of unfair dealing or improper use of information. The Code of Ethics requires employees to comply with all applicable laws, rules, and regulations wherever in the world we conduct business. This includes applicable laws on privacy and data protection, anti-corruption and anti-bribery, and trade sanctions.

If we make substantive amendments to the Code of Ethics, or grant any waiver, including any implicit waiver, from a provision of the Code of Ethics to our named executive officers, directors, financial professionals, and persons performing similar functions, we will disclose the nature of such amendment or waiver on our website or in a report filed with the SEC on Form 8-K.

We provide our Corporate Governance Guidelines, as well as the charters of each of our Board committees and our Code of Ethics on our website at https://www.riotblockchain.com/investors/corporate-governance. Information contained on or accessible via our website is not incorporated by reference into this Proxy Statement or any other report we file with the SEC.

The Board oversees the management of the business and affairs of the Company. In this oversight role, the Board serves as the ultimate decision-making body of the Company, except for those matters reserved for the stockholders. Our Board has been focused on, and committed to, responsible and effective corporate governance. Our Board members conduct candid and constructive discussions and deliberations among themselves and with management and outside advisors regarding the strategic vision of the Company and in fulfilment of their oversight role with respect to the Company’s executive officers.

Further, our Board operates with a robust committee structure consisting of the Board’s three standing committees, Audit, Compensation and Human Resources, and Governance and Nominating, each of which fulfill various aspects of the Board’s overall oversight and strategic roles. Each committee elects a chair from among its members to oversee and set the agendas for the committee’s meetings. As part of the Board’s role in overseeing the governance and structure of our business, the Board oversees the Company’s executive officers, including overseeing the partitioning of the various executive officers’ roles and responsibilities within the Company.

Our Board has adopted Corporate Governance Guidelines based on the best practices in our industry and the Board continues to review and adapt them over time. Our Governance and Nominating Committee is responsible for overseeing our Corporate Governance Guidelines, reporting and making recommendations to our Board concerning corporate governance matters. Our Board regularly reviews our Corporate Governance Guidelines and updates them periodically in response to changing regulatory requirements and evolving governance practices. Our Corporate Governance Guidelines, Articles of Incorporation and Bylaws address various governance matters including, but not limited to, the following:

A copy of our Corporate Governance Guidelines is available online at https://www.riotblockchain.com/investors/corporate-governance.

Each member of our Board is required to participate in board orientation programs which are designed to familiarize new Board members with the Company’s business, strategies, and policies which provides new Board members assistance in developing Company and industry knowledge to optimize their service on the Board. The Governance and Nominating Committee and management are responsible for maintaining the director orientation programs as well as director continuing education programs. The Board continuing education programs assist in maintaining and enhancing skills necessary to perform Board responsibilities. Continuing education programs may include internally developed programs, programs presented by third parties, and financial and administrative support to attend qualifying academic or other independent programs.

Our Bylaws provide that the Board is responsible for setting the size of the Board and for nominating individuals to stand for election to the Board by our stockholders. The Board has set the number of directors at five and is currently comprised of three non-employee independent directors and two executive directors who serve as part of our executive management team.

Our Bylaws also provide for a classified board, comprised of three approximately equal-in-size classes of directors (Class I, Class II, and Class III), with one of the three classes of directors standing for election at each annual general meeting of stockholders. At this time, the Board believes that the classified board structure is in the best interest of the Company. The classified board structure and corresponding terms will ensure that at any given time the majority of the directors will have deep knowledge of the Company and a firm understanding of its goals, and it allows for continuity and stability of the Board, promoting the balance of long-term and short-term interests of the Company and its stockholders. The structure also safeguards the Company from third-party takeover attempts, as it will require a longer period to change majority control of the Board. A classified board remains accountable to the Company’s stockholders as directors continue to have a fiduciary responsibility to the stockholders.

Our Bylaws further provide that the Board may establish committees from time to time as it deems necessary or expedient. Currently, the Board has established three standing committees, the Audit Committee, the Governance and Nominating Committee, and the Compensation Committee, each of which are comprised solely of independent directors. Our Bylaws provide that at least three directors serving on the Board must be “independent directors”

within the meaning of the Nasdaq continued listing standards and stock market rules (the “Nasdaq Market Rules”) and applicable SEC rules and regulations. The Board, upon recommendation of the Governance and Nominating Committee, unanimously determined that each of our three (3) non-employee directors is “independent,” as such term is defined in the Nasdaq Market Rules and the applicable SEC rules.

The definition of “independent director” included in the Nasdaq Market Rules includes a series of objective tests, such as whether the director is not an employee of the Company, has not engaged in various types of specified business dealings with the Company, and does not have an affiliation with an organization that has had specified business dealings with the Company. Consistent with the Company’s Corporate Governance Principles, the Board’s determination of independence is made in accordance with the Nasdaq Market Rules and the applicable SEC rules. Even though the Governance and Nominating Committee and the Board have determined that each of the nominated directors are “independent” according to the objective tests included in the Nasdaq Market Rules, the Board, as required by the Nasdaq Market Rules, has also made a subjective determination with respect to each director that such director has no material relationship with the Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company) and therefore meets the standards of independence required of “independent” directors under the Nasdaq Market Rules.

Additionally, the Board has affirmatively determined that each of the three members of its three standing committees, Ms. Hannah Cho, Mr. Hubert Marleau, and Mr. Lance D’Ambrosio, are each deemed “independent” (as that term is defined under the applicable rules and regulations of the SEC and the Nasdaq Market Rules, including the additional Audit Committee member and Compensation Committee member independence standards set forth in the Nasdaq continued listing standards).

Our Board’s leadership is currently comprised of our Executive Chairman, Benjamin Yi, and a Lead Independent Director, Hubert Marleau, each of whom were elected from the directors on the Board. Following the appointment of Benjamin Yi as our Executive Chairman in May 2021, the Board appointed Hubert Marleau to serve as the Lead Independent Director on our Board, having considered his strong leadership, independent presence and financial and business expertise on the Board. Mr. Marleau, together with Mr. Yi and our Chief Executive Officer, Jason Les (who also serves as an executive director on our Board), comprise our senior Board leadership, which the Board believes is appropriate at this time to provide the most effective leadership structure for the Company, which operates in a highly competitive and rapidly changing technology industry.

The Executive Chairman oversees and sets the agendas for the meetings of the Board, and the Lead Independent Director fills the Executive Chairman’s role under the circumstances outlined below. As Lead Independent Director for the Board, Mr. Marleau is responsible for overseeing the conduct of meetings where our Bylaws, Nasdaq Market Rules, applicable SEC rules and regulations, or Nevada law require our Executive Chairman, Mr. Yi, to be absent. During such meetings, Mr. Marleau has broad authority and oversight over the affairs of the Board. The Board believes its actions in adapting its leadership structure in response to the changes in its leadership and the challenges faced by the Company are evidence of its proactive commitment to strong corporate governance and appropriate independent director oversight of management.

The Board plays an active role in risk oversight of the Company. The Board does not have a formal risk management committee, but rather administers this oversight function through it three standing committees, the Audit Committee, the Governance and Nominating Committee, and the Compensation Committee, which are described below.

Our Board believes the following are certain key factors providing it appropriate opportunities for oversight, discussion and evaluation of Riot’s decisions and direction: (i) director independence, experience and knowledge; (ii) the ability of independent directors to participate in the agenda-setting process for our Board and committee meetings; (iii) the conduct of regularly scheduled executive sessions of independent directors; and (iv) our directors’ access to management.

The Board’s three standing committees play a key role in fulfilling the Board’s risk oversight function. Below is a brief description of the roles and activities of the Board’s standing committees in fulfilling this function. A more complete description of each of the committees can be found beginning on page 17 below.

The Audit Committee periodically reviews overall enterprise risk management, in addition to maintaining responsibility for oversight of financial reporting-related risks, including those related to the Company’s accounting, auditing and financial reporting practices. The Audit Committee also reviews reports and considers any material allegations regarding potential violations of the Company’s Code of Ethics and Business Conduct.

The Governance and Nominating Committee oversees corporate governance risks and oversees and advises the Board with respect to the Company’s policies and practices regarding significant issues of corporate responsibility.

The Compensation and Human Resources Committee oversees the Company’s compensation practices, including establishing and overseeing performance-oriented incentives to attract and retain highly qualified personnel for positions of substantial responsibility with the Company, evaluating and making recommendations to the Board with respect to incentive-compensation plans and equity-based plans, evaluating risks associated with the Company’s compensation policies and programs, and evaluating the adequacy of its current executive compensation and benefit plan, policies and programs. The Committee also oversees the Company’s personnel development and training, its human resources practices, including oversight of its management succession planning, and the maintenance of the Company’s corporate culture.

Our Board and its three standing committees meet throughout the year on a set schedule and also hold special meetings and may act by written consent from time to time as appropriate. Directors are expected to attend regular Board meetings and meetings of the committees on which they serve, with the understanding that, on occasion, a director may be unable to attend a meeting. In 2021, the Board held 17 regular meetings and also took additional actions by unanimous written consent, as permitted by our Bylaws and Nevada law. Each director attended 100% of the regular and special meetings of the Board and of the committees on which he or she served that were held during his or her term of office. All directors then-serving attended last year’s annual general meeting of stockholders, and, to the Company’s knowledge, all of our current directors will attend this year’s Annual Meeting.

In addition to formal meetings of the Board and its three standing committees, directors meet and confer on an informal basis throughout the year. While no formal business is decided at these informal meetings, the Board believes participating in them better enables its members to carry out the Board’s oversight functions and to more rapidly respond to emerging opportunities and challenges facing the Company as they arise.

The Board also holds executive sessions of its members qualified as “independent directors” within the meaning of the Nasdaq Market Rules and applicable SEC rules and regulations in connection with regularly scheduled Board meetings and at such other times as they deem appropriate. Executive sessions of independent directors are provided for in the agenda for each regularly scheduled Board meeting. Each of the independent directors attended 100% of the regular and special executive sessions that were held during his or her term of office.

An important part of the executive sessions of independent directors of our Board and its three standing committees is the discussion of results from the annual self-evaluations undertaken by our Board and its standing committees, the design of which is for continuous improvement in performance and effectiveness. Our Governance and Nominating Committee facilitates our Board’s annual self-evaluation.

Should stockholders wish to communicate with the Board, correspondence may be sent to the Board of Directors at: Riot Blockchain, Inc., 3855 Ambrosia Street, Suite 301, Castle Rock, Colorado 80109, Attention: Board of Directors, and specifically request that a copy of the letter be distributed to a particular Board member or to all Board members. Where no such specific request is made, the letter will be distributed to all Board members if material, in the judgment of the Chief Executive Officer, to matters on the Board’s agenda.

Our Board has three standing committees: (i) the Audit Committee, (ii) the Governance and Nominating Committee, and (iii) the Compensation Committee. Each of these three standing committees is comprised solely of and chaired by non-employee independent directors, each of whom the Board has affirmatively determined is independent pursuant to the Nasdaq Market Rules and applicable SEC regulations. Each of the committees operates pursuant to its charter. The committees regularly report their activities and actions to our full Board, generally at the next Board meeting following a committee meeting. The committee charters are reviewed annually by the Governance and Nominating Committee. If appropriate, and in consultation with the chairs of the other committees, the Governance and Nominating Committee proposes revisions to the charters. The responsibilities of each committee are described in more detail below. The charter of each of our Audit Committee, Governance and Nominating Committee, and Compensation Committee complies with applicable Nasdaq Market Rules, SEC regulations and provisions of Nevada corporate law.

Copies of each of the charters for the three standing committees are available at https://www.riotblockchain.com/ investors/corporate-governance, by following the link for each of the Audit Committee, the Governance and Nominating Committee, and the Compensation Committee, and are also available to stockholders free of charge upon written request to our Corporate Secretary at Riot Blockchain, Inc., Attention: Corporate Secretary, 3855 Ambrosia Street, Suite 301, Castle Rock, Colorado 80109. The principal functions of each of the three standing committee are summarized below.

The Company’s Audit Committee currently consists of the following three independent directors: Lance D’Ambrosio, Hubert Marleau and Hannah Cho, with Mr. D’Ambrosio serving as the Audit Committee’s Chair. Our Audit Committee oversees our independent registered public accounting firm and accounting and internal control matters. Our Audit Committee also assists our Board in fulfilling its responsibilities to oversee, among other things, oversight over: the integrity of our financial statements; our compliance with relevant legal and regulatory requirements; our internal controls over financial reporting; the qualifications and independence of our independent registered public accounting firm; and the performance of our internal audit function and the audit function of our independent registered public accounting firm.

In addition to these key oversight functions, our Audit Committee is responsible for, among other matters, the following:

A more detailed description of our Audit Committee’s purposes and responsibilities is contained in its charter, which is available online at https://www.riotblockchain.com/investors/corporate-governance.

The Board has affirmatively determined in its business judgment that each member of the Audit Committee meets the additional independence criteria applicable to audit committee members under SEC rules, the Sarbanes-Oxley Act of 2002, and the Nasdaq Market Rules. The Board has determined, in its business judgment, that Mr. D’Ambrosio of the Audit Committee meets the qualifications of an “audit committee financial expert,” as that term is defined under the SEC rules, and that all three members of the Audit Committee are independent of Riot.

The Audit Committee held twelve (12) meetings (including by written consent) during the fiscal year ended December 31, 2021, and four (4) meetings (including by written consent) to date in the fiscal year ending December 31, 2022, including meeting regularly with the Company’s Auditor, both privately and with representatives of the Company’s management present.

The Company’s Compensation Committee currently consists of the following three independent directors, each of whom the Board has determined meet the director independence requirements of the Nasdaq Market Rules and applicable SEC regulations for service on a public company’s compensation committee: Hannah Cho, Lance D’Ambrosio and Hubert Marleau, with Ms. Cho serving as the committee’s Chair. The Compensation Committee, among other things, is responsible for:

A more detailed description of our Compensation Committee’s purposes and responsibilities is contained within its charter, which is available online at https://www.riotblockchain.com/investors/corporate-governance.

When evaluating the compensation of our executive officers, the Compensation Committee evaluates factors including the executive’s responsibilities, experience, and the competitive marketplace. The Compensation Committee may also invite the senior executives and other members of management to participate in their deliberations, or to provide information to the Compensation Committee for its consideration with respect to such deliberations, except that the Executive Chairman and Chief Executive Officer may not be present for the deliberation of or the voting with respect to his or her compensation. The Executive Chairman and Chief Executive Officer may, however, be present for the deliberation of or the voting on compensation for any other person, including other executive officers, if any.

The Compensation Committee has authority to retain such compensation consultants, outside counsel and other advisors as the Compensation Committee in its sole discretion deems appropriate. The Compensation Committee retained Meridian Compensation Partners, LLC (“Meridian”) in connection with the preparation of the Riot Blockchain, Inc. 2019 Equity Plan, which was ratified and approved by the stockholders at the 2019 Annual General Meeting, the First Amendment to the Riot Blockchain, Inc. 2019 Equity Plan, which was ratified and approved by the stockholders at the 2020 Annual General Meeting, and the Second Amendment to the Riot Blockchain, Inc. 2019 Equity Plan, which was ratified and approved by stockholders at the 2021 Annual General Meeting. The Compensation Committee’s retention of Meridian as its compensation advisor with respect to the Compensation Committee’s evaluation of the Company’s compensation practices, including its equity incentive compensation planning, is pursuant to a direct engagement agreement between the committee and Meridian. The Compensation Committee has instructed Meridian to provide comparative information regarding companies of similar size and in related industries as Riot and to analyze the Company’s historical and current compensation to assist the

Compensation Committee with its evaluation of the Company’s compensation practices and future needs. The Board has affirmatively determined that each member of the Compensation Committee meets the additional independence criteria applicable to Compensation Committee members under the Nasdaq Market Rules and the applicable SEC rules.

The Compensation Committee held seventeen (17) meetings (including by written consent) during the fiscal year ended December 31, 2021, and five (5) meetings (including by written consent) to date in the fiscal year ending December 31, 2022.

The Company’s Governance and Nominating Committee currently consists of the following independent directors, each of whom the Board has determined meet the director independence requirements of the Nasdaq Market Rules and applicable SEC regulations for service on a public company’s governance and nominating committee: Hubert Marleau, Lance D’Ambrosio, and Hannah Cho. Mr. Marleau serves as Chair of the Governance and Nominating Committee. The Governance and Nominating Committee, among other things, is responsible for:

A more detailed description of our Governance and Nominating Committee’s purposes and responsibilities is contained within its charter, which is available at our website at: https://www.riotblockchain.com/investors/corporategovernance.

The Board has affirmatively determined that each member of the Governance and Nominating Committee meets the independence criteria applicable to governance and nominating committee members under the Nasdaq Market Rules and applicable SEC rules.

The Governance and Nominating Committee held six (6) meetings (including by written consent) during the fiscal year ended December 31, 2021, and one (1) meeting (including by written consent) to date in the fiscal year ending December 31, 2022.

As specified in our Corporate Governance Guidelines, we seek directors with the highest standards of ethics and integrity, sound business judgment, and the willingness to make a strong commitment to the Company and its success. The Governance and Nominating Committee works with the Board on an annual basis to determine the appropriate and desirable mix of characteristics, skills, expertise, and experience for the full Board and each committee, taking into account both existing directors and all nominees for election as directors, as well as any diversity considerations and the membership criteria reflected in the Corporate Governance Guidelines. The Governance and Nominating Committee and the Board, which do not have a formal diversity policy, consider diversity in a broad sense when evaluating board composition and nominations; they seek to include directors with a diversity of experience, professions, viewpoints, skills, and backgrounds that will enable them to make significant contributions to the Board

and the Company, both as individuals and as part of a group of directors. The Board evaluates each individual in the context of the full Board, with the objective of recommending a group that can best contribute to the success of the business and represent stockholder interests through the exercise of sound judgment. In determining whether to recommend a director for re-election, the Governance and Nominating Committee also considers the director’s attendance at meetings and participation in and contributions to the activities of the Board and its committees.

The Governance and Nominating Committee will consider director candidates properly recommended by stockholders by providing notices of stockholder proposals in compliance with our Bylaws applicable law. The Governance and Nominating Committee’s process for considering such stockholder recommendations is no different than its process for screening and evaluating candidates suggested by directors, our management, or third parties.

All of the services performed in the years ended December 31, 2021 and December 31, 2020 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 the 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 the independent registered public accounting firm’s independence.

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, 2021, as amended on Form 10-K/A, 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, 2022. The Audit Committee also has appointed, and has requested stockholder ratification of the appointment of, Marcum as Riot’s independent registered public accounting firm for the fiscal year ending December 31, 2022.

Under the Nevada Revised Statutes, our stockholders are not entitled to appraisal rights with respect to our proposed ratification of the appointment of Marcum LLP as our independent registered public accounting firm, and we will not independently provide our stockholders with any such rights.

The affirmative vote of a majority of the votes cast for this proposal is required to ratify the appointment of the Company’s independent registered public accounting firm. Abstentions will be counted towards the tabulation of votes cast on this proposal but will have no effect on the outcome of the vote on this proposal. Brokerage firms have authority to vote customers’ unvoted shares held by the firms in street name on this proposal. If a broker does not exercise this authority, such broker non-votes will have no effect on the results of this vote.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF MARCUM LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM, AND PROXIES SOLICITED BY THE BOARD WILL BE VOTED IN FAVOR THEREOF UNLESS A STOCKHOLDER HAS INDICATED OTHERWISE ON THE PROXY.

This Compensation Discussion and Analysis provides an overview of our executive compensation program for fiscal year 2021 and our executive compensation philosophies and objectives, as well as the compensation awarded to our fiscal year 2021 Named Executive Officers (the “NEOs”) (within the meaning of Item 402(a)(3) of Regulation S-K), who are listed below.

The Board has delegated to its Compensation 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 Committee evaluates factors including the executive’s responsibilities, experience and the competitive marketplace. The Compensation 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 Committee for its consideration with respect to such deliberations, except that the Executive Chairman and Chief Executive Officer may not be present for the Compensation 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 Committee has authority to retain such compensation consultants, outside counsel and other advisors as the Compensation Committee in its sole discretion deems appropriate.

On an annual basis, the Compensation Committee directs its compensation consultant, Meridian, to review the Company’s compensation practices. Based on Meridian’s assessment, the Compensation Committee determines whether the overall executive compensation program is consistent with our business strategy and objectives and promotes our compensation philosophy. The Compensation 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.

Taking into consideration the independence factors in the Nasdaq Market Rules, the Compensation Committee has made the determination that, in its business judgment, Meridian was independent and that its work did not raise any conflicts of interest.

At the 2021 Annual General Meeting, the Company’s stockholders approved the advisory proposal regarding the compensation of the Company’s NEOs with approximately 94.2% of the votes cast in favor of our executive compensation programs (excluding abstentions/broker non-votes). The Board appreciates the stockholders’ continued support of the Company’s compensation philosophy and objectives. This support reaffirms to the Board the appropriateness, effectiveness and market competitiveness of the Company’s executive compensation programs, including continued emphasis on programs that reward our executive officers for generating sustainable profitability and delivering long-term value for our stockholders. The Board and the Compensation Committee will continue to consider the results of the Company’s annual stockholder advisory votes when making future compensation decisions for our executive officers, including the NEOs.

The Compensation Committee evaluates the Company’s executive compensation programs in comparison to those of a select peer group consisting of fourteen similarly situated professional services companies. The peer group is used to compare total direct compensation and the mix of compensation elements for each NEO against peer group positions with similar responsibilities.

We established stock ownership requirements to ensure that our NEOs hold a meaningful equity stake in the Company and, by doing so, link their interests with those of our stockholders. Stock directly or indirectly owned (for example, through a trust), along with unvested RSUs (if any), are included in the calculation of ordinary shares owned for purposes of the ownership requirements. NEOs are expected to meet the ownership requirements within five (5) years of the date upon which the NEO first becomes subject to the requirements.

Our NEOs are required to own shares in an amount equal to an applicable target value based on a multiple of annual base salary. Our NEOs are required to meet the requirements by the following ownership requirement dates.

The Company currently has one equity compensation plan, the 2019 Equity Plan, as amended. On October 19, 2021, the Company’s stockholders approved the Second Amendment, which increased the number of shares of the Company’s common stock reserved for issuance by 4,400,000 shares. The Company currently provides stock-based compensation to employees, directors and consultants under the 2019 Equity Plan, as approved by the Company’s stockholders on October 23, 2019, and on November 12, 2020 with respect to the First Amendment, and on October 19, 2021 with respect to the Second Amendment. The Company’s previous 2017 Stock Incentive Plan, as amended (the “2017 Plan”), was replaced by the 2019 Plan, with the 2017 Plan continuing to govern the then

outstanding grants and awards for 12,000 options and 114,103 shares of restricted common stock. No additional grants can be made under the 2017 Plan. The Company has reserved 3,554,111 common shares for issuance under the 2019 Plan.

The following table provides information as of December 31, 2021, about the shares of common stock that may be issued upon the vesting of performance and non-performance based restricted common stock under the 2019 Equity Plan:

The Company currently has one equity compensation plan, the Riot Blockchain, Inc. 2019 Equity Plan, as approved by the stockholders at the 2019 Annual General Meeting of stockholders, including the First Amendment to the Riot Blockchain, Inc. 2019 Equity Plan, as approved by the stockholders at the 2020 Annual General Meeting of stockholders (collectively, the “2019 Equity Plan”). Under the 2019 Equity Plan, the Company may provide stock-based compensation to employees, directors and consultants. The Company’s previous 2017 Stock Incentive Plan, as amended, (the “2017 Equity Incentive Plan”), was replaced by the 2019 Equity Plan, with the 2017 Equity Incentive Plan continuing to govern the then outstanding grants and awards for 12,000 options and 288,603 shares of restricted common stock made under the 2017 Equity Incentive Plan. As of the date of adoption of the 2019 Equity Plan, no additional grants may be made under the 2017 Equity Incentive Plan. As approved by the Company’s stockholders at the 2019 Annual General Meeting, the Company reserved 3,600,000 shares of its common stock for issuance under the 2019 Equity Plan, and, as approved by the Company’s stockholders at the 2020 Annual General Meeting, the number of shares reserved for issuance under the 2019 Equity Plan was increased by 3,500,000 additional shares. As of the date of this Proxy Statement, the Company has granted awards of 3,860,000 restricted stock units and, as discussed under the following section, of performance-based restricted stock units, under the 2019 Equity Plan which are, upon vesting and settlement by the Company, convertible into an equal number of shares of the Company’s common stock.

On August 12, 2021, we adopted a performance-based restricted stock unit performance plan (the “Performance RSU Plan”) for all executive officers and eligible employees of the Company and its consolidated subsidiaries. In connection with the Performance RSU Plan, a form of performance-based restricted stock unit award agreement was approved (the “Performance RSU Award Agreement”) under the 2019 Equity Plan, which are eligible to vest during the performance period ending December 31, 2023 (the “Performance Period”) based upon the Company achieving certain performance goals, as further described below.

The Performance RSU Award Agreement provides for the grant of Performance RSU Awards, which generally vest upon the successful completion of specified milestones for each 100 megawatts (“MW”) of added infrastructure capacity, up to a total capacity of 1,500 MW (as described in the Performance RSU Award Agreement) (the “Infrastructure Development Target”). The Performance RSU Award Agreement also provides for the grant of Performance RSU Awards which generally vest if the Company achieves specified thresholds of Adjusted EBITDA (as described in the Performance RSU Award Agreement) (“Adjusted EBITDA”). The vesting and issuance of shares of common stock to the award participant only occurs if the Company achieves specified thresholds of the Infrastructure Development Target and Adjusted EBITDA target during the Performance Period.

The exact number of shares issuable pursuant to the Performance RSU Award Agreement depends on level of the Company’s performance against the Infrastructure Development Target and Adjusted EBITDA target, as determined by the Compensation Committee during the Performance Period, and in general can range from 0% to 100% of the target number of Performance RSU Awards, depending on the level of achievement of the Infrastructure Development Target and Adjusted EBITDA targets. If the Infrastructure Development Target or Adjusted EBITDA target have not been met by the end of the Performance Period, any unvested Performance RSU Awards are forfeited. The foregoing description is subject to, and qualified in its entirety by, the information contained in the Form 8-K, filed August 16, 2021.

As of the filing of this Proxy Statement, the Compensation Committee has determined that the performance objectives for a total of 319,026 Performance RSU Awards granted to our officers and employees under the Performance RSU Plan have been achieved; and, therefore, that these 319,026 Performance RSUs have become vested and are eligible to be settled by the Company under the 2019 Equity Plan.

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 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.

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.
