Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Pursuant to the Riot Blockchain, Inc. 2019 Equity Incentive Plan, as amended, (the "Equity Plan") each performance-based restricted stock unit ("PSUs") represents a contingent right to receive one share of the Issuer's common stock, no par value per share, ("Common Stock") upon settlement by the Issuer following vesting. PSUs are subject to vesting under the performance plan established by the Issuer's Compensation and Human Resources Committee (the "Committee") under the Equity Plan, (the "Performance Plan") in connection with the Issuer's achievement of certain performance milestones specified by the Committee during the performance period expiring on December 31, 2023.
(2) On July 13, 2022, the Committee determined that the Issuer had achieved, as of June 30, 2022, the performance criteria corresponding to 16,666 PSUs. Upon vesting, the Issuer records PSUs as Restricted Stock Units, which are eligible to be settled by the Issuer in shares of its Common Stock on a one-for-one basis, subject to any net settlement for taxes as permitted under the Plan and as approved by the Committee. Accordingly, the award of 16,666 Restricted Stock Units reported on this Form 4 represents the vesting of 16,666 PSUs awarded to the Reporting Person on August 12, 2021.
(3) Represents the total direct and indirect beneficial ownership of the indicated security held by the Reporting Person immediately following the eported transaction.
