Inc.” and “Riot” mean Riot Blockchain, Inc. and its consolidated subsidiaries, unless otherwise indicated.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING
STATEMENTS

This Amendment No. 1 to our Annual Report
on Form 10-K contains certain statements that are, or may be deemed to be, forward-looking statements within the meaning of Section
27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act
of 1934, as amended (the “Exchange Act”). These forward-looking statements (such as when we describe what “will,”
“may,” or “should” occur, what we “plan,” “intend,” “estimate,” “believe,”
“expect” or “anticipate” will occur, and other similar statements) include, but are not limited to, statements
regarding future operating results, potential risks pertaining to these future operating results, future plans or prospects, anticipated
benefits of proposed (or future) acquisitions, dispositions and new facilities, growth, the capabilities and capacities of business
operations, any financial or other guidance, expected capital expenditures and all statements that are not based on historical
fact, but rather reflect our current expectations concerning future results and events. We make certain assumptions when making
forward-looking statements, any of which could prove inaccurate, including assumptions about our future operating results and business
plans. Therefore, we can give no assurance that the results implied by these forward-looking statements will be realized. Furthermore,
the inclusion of forward-looking information should not be regarded as a representation by the Company or any other person that
future events, plans or expectations contemplated by the Company will be achieved. The following important factors, among others,
could affect future results and events, causing those results and events to differ materially from those expressed or implied in
our forward-looking statements:

|· | our ability to achieve profitability in the future;                                                                                                                                                                                             
|- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|· | high volatility in the value attributable to our business;                                                                                                                                                                                      
|· | the rapidly changing regulatory and legal environment in which we operate, may lead to unknown future challenges to operating our business or which may subject our business to added costs and/or uncertainty regarding the ability to operate;
|· | risks related to our failure to continue obtaining financing on a timely basis and on acceptable terms;                                                                                                                                         
|· | our ability to keep pace with technology changes and competitive conditions;                                                                                                                                                                    
|· | our ability to execute on our business strategy;                                                                                                                                                                                                
|· | other risks and uncertainties related to our business plan and business strategy.                                                                                                                                                               
|· | our expectation
    regarding the impact of a novel strain of coronavirus (“COVID-19”)                                                                                                                                                          



For a further list and description of
various risks, factors and uncertainties that could cause future results or events to differ materially from those expressed or
implied in our forward-looking statements, see the “Risk Factors” and “Management’s Discussion and Analysis
of Financial Condition and Results of Operations” sections contained in the Original Filing, and any subsequent reports on
Form 10-Q and Form 8-K, and other filings we make with the Securities and Exchange Commission (“SEC”), which are incorporated
by reference into this Amendment. Given these risks and uncertainties, the reader should not place undue reliance on these forward-looking
statements.

All forward-looking statements included
in this Amendment are made only as of the date of this Amendment to our Annual Report, and we do not undertake any obligation to
publicly update or correct any forward-looking statements to reflect events or circumstances that subsequently occur, or of which
we hereafter become aware. You should read this document completely and with the understanding that our actual future results or
events may be materially different from what we expect. All forward-looking statements attributable to us are expressly qualified
by these cautionary statements.

Corporate Governance Policies and
Code of Ethics

We have adopted a Standard of Ethics
and Business Conduct, Corporate Governance Guidelines. Those policies are available on our website at www.riotblockchain.com and
in print to any stockholder upon request at no charge. Requests should be addressed to: Riot Blockchain, Inc., 202 6th Street,

Independence of Directors

The Company’s Board is currently
comprised of three independent directors: (i) Mr. Remo Mancini; (ii) Mr. Jason Les; and (iii) Mr. Benjamin Yi.  Mr. Mancini
serves as Chairman of the Board.

The Board, upon recommendation of the
Governance and Nominating Committee, unanimously determined that each of our three non-employee directors is “independent,”
as such term is defined in the Nasdaq Stock Market Rules (“Stock Market Rules”) and applicable SEC rules.

The definition of “independent
director” included in the Stock Market Rules includes a series of objective tests, such as whether the director is an employee
of the Company, whether the director has engaged in various types of specified business dealings with the Company, and whether
the director has 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 Stock Market Rules, as the Board has not adopted supplemental independence standards. As required by the Stock Market Rules,
the Board also has 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),
even if the director otherwise satisfies the objective independence tests included in the definition of an “independent director”
included in the Stock Market Rules.

In determining that each individual
who served as a member of the Board is independent, the Board considered that, in the ordinary course of business, transactions
may occur between the Company and entities with which some of our directors are affiliated. The Board unanimously determined that
such transaction occurring in the ordinary course of business with members of the Board were not material. No unusual discounts
or terms were extended to members of the Board by the Company in any such transactions.

Board Leadership Structure

The Board believes that the Company’s
stockholders are best served if the Board retains the flexibility to adapt its leadership structure to applicable facts and circumstances,
which necessarily change over time. Accordingly, the Company’s Corporate Governance Principles provide that the Board may
combine or separate the roles of the CEO and Chairman of the Board, and it may suspend, dissolve and form separate committees of
the Board as it deems advisable and in the best interests of the Company and its stockholders.

Board Role in Risk Oversight

The Company’s 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 various standing committees of the Board, which are described 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.
The Compensation Committee oversees risks arising from the Company’s compensation policies and programs. This Committee has
responsibility for evaluating and approving the executive compensation and benefit plans, policies and programs of the Company.
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 Board of Directors has a process
for stockholders to communicate with directors. Stockholders should write to the Chief Executive Officer of the Company at the
Company’s mailing address 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 Board members if material, in
the judgment of the Chief Executive Officer, to matters on the Board’s agenda.

Committees of the Board

Our Board has three standing committees:
Audit, Compensation, and Governance and Nominating. Each of the committees is solely comprised of and chaired by independent directors,
each of whom the Board has affirmatively determined is independent pursuant to the Stock Market Rules. Each of the committees operates
pursuant to its charter. 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 of the standing committees of the Board are described in more detail below. The charters
for the three committees are available on the Company’s website at www.riotblockchain.comby following the
link to “Investor Relations” and then to “Governance.”

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities
Exchange Act of 1934 requires the Company’s directors, named executive officers, and stockholders who own 10% or more
of the Company’s stock to file forms with the SEC to report their ownership of the Company’s stock and any
changes in their ownership of our securities. The Company assists its directors and executives by identifying reportable
transactions of which it is aware and preparing and filing the forms on their behalf. All persons required to file forms with
the SEC must also send copies of the forms to the Company. We have reviewed all forms provided to us. Based on that review
and on written information given to us by our executive officers and directors, we believe that all Section 16(a) filings
during the past fiscal year were filed on a timely basis and that all directors, executive officers and 10% beneficial owners
have fully complied with such requirements during the past fiscal year.

(“ASC 718”). See Note 12 to our consolidated financial statements reported in our Annual Report on Form 10-K for our
fiscal year ended December 31, 2019, for details as to the assumptions used to determine the grant date fair value of the restricted
stock awards. According to ASC 718, the value of Stock Awards is reported as of the date of grant based on the last reported trading
price of our securities on the Nasdaq Capital Market, excluding the effect of possible forfeitures. Recipients of such Stock Awards
may, therefore, experience diminution in value of their Stock Awards over time based on fluctuations in the trading price of our
securities.

columns reflect the grant date fair value for all stock option awards granted under the 2017 Equity Incentive Plan during 2018.

Assumptions used in the calculation of the amounts in these columns for 2018 are included in footnote 12 to the Company’s
audited financial statements for the fiscal year ended December 31, 2019 included in the Company’s Annual Report on Form
10-K for the year ended December 31, 2019. According to ASC 718, the value of Option Awards is reported as of the date of grant
based on the last reported trading price of our securities on the Nasdaq Capital Market, excluding the effect of possible forfeitures.
Recipients of such Option Awards may, therefore, experience diminution in value of their Option Awards over time based on fluctuations
in the trading price of our securities.

Securities Authorized Under Equity Compensation Plans
Information

The Company currently has one current equity
compensation plan, the Riot Blockchain, Inc. 2019 Equity Incentive Plan (the “2019 Plan”), as approved by the Company’s
stockholders on October 23, 2019. Under the Plan, the Company may provide stock-based compensation to employees, directors and
consultants. The Company’s previous 2017 Stock Incentive Plan, as amended, was replaced by the 2019 Plan, with the 2017 Stock
Incentive Plan (the “2017 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 Plan. As of the date of adoption of the 2019 Plan, no additional
grants may be made under the 2017 Plan. As approved by the Company’s stockholders during the 2019 Annual Meeting, the Company
reserved 3,600,000 shares of its Common Stock for issuance under the 2019 Plan. The Company has granted convertible rights to receive
1,493,832 of these reserved shares of its Common Stock upon vesting and settlement under the 2019 Plan; 2,106,168 of the reserved
shares of its Common Stock therefore remain issuable under the 2019 Plan as of December 31, 2019.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED
TRANSACTIONS, AND DIRECTOR INDEPENDENCE.

Certain Relationships and Related Transactions

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 Named Executive Officers, Directors, or stockholders
(or groups of stockholders) owning 5% or more 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 are available on the Company’s web site.

Since the beginning of the Company’s
last fiscal year, no transactions with a Related Party were approved by the Audit Committee. Other than the compensation arrangements
described under the section entitled “Executive Compensation” herein, and standard indemnification agreements with
our directors and officers, there were no transactions with a Related Party in which a Related Party had or will have a direct
or indirect material interest in the Company.

Director Independence

Information about the independence of
our non-employee directors and the composition of the Audit Committee and Compensation Committee is set forth in Item 10,
“Directors, Named Executive Officers, and Corporate Governance” herein.

ITEM 14.  PRINCIPAL ACCOUNTANT
FEES AND SERVICES.

The Company’s Audit Committee
currently has a policy in place that requires its review and pre-approval of all audit and permissible non-audit services provided
by its independent auditors.  These services requiring pre-approval by the Audit Committee may include audit services, audit
related services, tax services and other services.  All of the services performed by the independent registered public accounting
firm were approved by the Company’s Audit Committee and prior to performance. The Audit Committee has determined that the
payments made to its independent accountants for these services are compatible with maintaining such auditors’ independence.

Aggregate fees billed or expected to
be billed for professional services for the years ended December 31, 2019 and 2018 in the following categories and amounts were:

|               |  | 2019 |         | 2018
|-------------- |  | ---- | ------- | ----
|               |  |      |         |     
|Audit Fees (1) |  | $    | 429,000 |     
|Tax Fees (2)   |  |      | 2,000   |     
|All Other Fees |  |      | —       |     
|Total Fees     |  | $    | 431,000 |     



| | (1) | Audit fees relate to the financial statement audits, the quarterly reviews and related matters. Audit fees include services rendered by Marcum LLP for the 2019 and 2018 audits totaling $296,000 and $491,000, respectively.  Fees also include services rendered by Marcum LLP for their reviews of the interim condensed consolidated financial statements included in the Company’s Form 10-Qs during the first three quarters of 2019 totaled $72,000 and services by MNP LLP (the Company’s prior auditor) for their reviews of the interim condensed consolidated financial statements included in the Company’s Form 10-Qs during the first three quarters of 2018 totaled $73,000. Audit
    fees include services, including services related to the review of our registration statements by Marcum LLP, MNP LLP and
    EisnerAmper LLP (the Company’s prior auditors) for 2019 totaled $42,000, $7,000 and $12,000, respectively.  Audit
    fees for review of our registration statements rendered by MNP LLP, EisnerAmper LLP and Crowe LLP (the Company’s prior
    auditors) for 2018 totaled $4,000, $67,000 and $3,000, respectively.
